TSL2PS(.x, xi = 0.05, Tn = NULL, output = "PSL", D50 = FALSE, D100 = FALSE, nTheta = 180L)
is the explicit response-spectrum helper for canonical TSL
tables produced by AT2TS(), VT2TS(), and
DT2TS(). It does not expose BY,
COL.s, COL.t, or COL.ID; grouping
metadata is derived from the TSL schema. Projects that
currently call
TS2PS(TSL, COL.s = "s", COL.t = "t", COL.ID = "ID", Output = "PSL")
for canonical TSL input should migrate to
TSL2PS(TSL, output = "PSL").TSL2PS()
contract. D50 migration:
TSL2PS(TSL, output = "PSL", D50 = TRUE, nTheta = 12L)
replaces TS2PS(..., D50 = TRUE, n.theta = 12L). This is a
breaking 0.4.6 migration note; other projects should read this changelog
before updating.TSL2TSW(), TSW2TSL(),
TSL2IM(), IML2IMW(), PSL2PSW(),
and PSW2PSL(). These replace local project helpers that
manually cast TSL, IML, and PSL
tables with repeated dcast() / melt()
code.TSL2TSW(.x, by = "auto", ids = c("AT", "VT", "DT"))
converts canonical long time-series tables (t,
s, ID, OCID) to wide
TSW columns such as AT.H1, VT.H1,
and DT.H1. TSW2TSL() reverses the projection
and accepts either t or legacy constructor ts
as the time column.
TSL2IM(.x, units.source, units.target = "mm", output = c("IML", "IMW"))
is the primary intensity API. getIntensity() remains as a
compatibility wrapper and keeps the long IML default. Use
output = "IMW" or IML2IMW() when a downstream
table needs one row per metadata and OCID.
PSL2PSW() and PSW2PSL() expose the
canonical spectra long/wide conversion. After PSW2PSL(),
D50 and D100 are ordinary OCID
values, so scripts can filter OCID %in% c("D50", "D100")
instead of parsing column-name suffixes.
TSL2PS() now accepts vector xi. A
scalar xi preserves the previous schema with no
xi column. A vector xi adds xi as
metadata:
TSL2PS(TSL, xi = c(0.02, 0.05, 0.10), output = "PSW",
D50 = TRUE, D100 = TRUE)Downstream scripts that currently loop over damping ratios can call
TSL2PS() once and group or filter by
xi.
TSL2PS() now adds D100 horizontal response spectra
beside the existing D50 path:
TSL2PS(TSL, output = "PSW", D50 = TRUE, D100 = TRUE, nTheta = 180L)output = "PSL" adds rows with
OCID = "D100". output = "PSW" adds
PSA.D100, PSV.D100, and SD.D100.
Scripts that already consume PSA.D50, PSV.D50,
or SD.D50 should explicitly include the matching D100
columns when they opt in.
Downstream configs/scripts that currently enumerate D50, such as
spectra.D50, DIR_TARGET = "D50", or
plot/export direction lists, should add D100 explicitly
only for runs that request D100 = TRUE.
D100 uses the same rotation grid as D50. It is the maximum over
rotated horizontal spectra for each period and spectral ID; the
maximizing angle can vary by Tn and by PSA /
PSV / SD. The implementation returns spectra
only, not the D100 angle. When D50 = TRUE and
D100 = TRUE, both derived components are computed from one
rotated response matrix.
The downstream contract stays canonical TSL2PS(). Do
not migrate scripts to TS2PS(), TS2PSA(),
RotD50, or RotD100 names. The implementation
plan is recorded in dev/SoT/PLAN-TSL2PS-D100.md.
getND() has been moved out of the exported package
surface to dev/legacy/get_ND.R. Its public signature mixed
raw heterogeneous units, target units, and Newmark episode controls in a
way that needs a separate design before returning to the
package.
mapOCIDtoDir() has been moved out of the exported
package surface to dev/legacy/mapOCIDtoDir.R.
mapComponents() now owns component classification, and
extractRecord() calls
mapComponents(..., rotate = FALSE) before alignment. The
new SoT compares classification against the old helper and verifies
byte-identical raw CSV/JSON outputs for fixture extraction.
mapComponents() now accepts
output = c("long", "wide") and can consume either long
t, OCID, s input or wide
t, <OCID1>, <OCID2>, <OCID3> input. The
default "long" shape remains the compatible output;
output = "wide" returns
data.table(t, H1, H2, UP). Both outputs preserve
componentMap and rotate attributes; rotated
outputs also preserve theta.
filterIMF() has been moved out of the exported
package surface to dev/legacy/filterIMF.R. No current
callers were detected in gmsp, AR-S2J2J, or
AR-SABP0.R; users should compose filtering workflows
directly from canonical TSL, TS2IMF(), and
TSL2PS().
The 0.4.x spectra path is closed around canonical
TSL consumption: spectra code should call
TSL2PS(), not TS2PS() with BY,
COL.s, COL.t, and
COL.ID.
TS2PS() has been removed from the exported package
surface. It mixed generic long-table dispatch, grouping autodetection,
column-name arguments, and D50 behavior. Use TSL2PS() with
canonical TSL input.
TS2IMF() is now a single-series worker over
canonical columns t and s. It no longer
exposes BY, COL.s, COL.t, or
Output; use output. Grouped callers should use
data.table grouping, for example
TSL[ID == "AT", TS2IMF(.SD, output = "TSL"), by = .(RecordID, OCID), .SDcols = c("t", "s")].
normalizeTS() now consumes canonical
TSL input directly:
normalizeTS(TSL, norm = "PGA"). It no longer exposes
COL.s, COL.ID, COL.OCID, or
BY; grouping is derived from metadata columns plus
OCID.
readTS(), readAT(),
readVT(), and readDT() now use .x
for the selection table and path for the records root. This
is a named-argument breaking change:
# before
readTS(SEL = SEL, recordsDir = RecordsDir, kind = "VT")
readAT(SEL, recordsDir = RecordsDir)
# after
readTS(.x = SEL, path = RecordsDir, kind = "VT")
readAT(.x = SEL, path = RecordsDir)Positional calls with both arguments, such as
readAT(SEL, RecordsDir), remain valid. The same
.x / path rule applies to
readVT() and readDT(); do not update callers
to keep recordsDir =.
buildMaster() now uses path for the
index root:
# before
buildMaster(indexDir = IndexDir, owners = Owner)
# after
buildMaster(path = IndexDir, owners = Owner)Positional calls such as
buildMaster(IndexDir, owners = Owner) remain valid. Named
callers must not keep indexDir =.
buildRawFileTable() now uses
path.records for the records root and
path.index for the index root:
# before
buildRawFileTable(recordsDir = RecordsDir, indexDir = IndexDir,
owners = Owner)
# after
buildRawFileTable(path.records = RecordsDir, path.index = IndexDir,
owners = Owner)Positional calls with both paths remain valid. Named callers must not
keep recordsDir = or indexDir =.
buildRawRecordTable() and
buildRawIntensityTable() now use the same path argument
contract as buildRawFileTable():
# before
buildRawRecordTable(recordsDir = RecordsDir, indexDir = IndexDir,
owners = Owner)
buildRawIntensityTable(recordsDir = RecordsDir, indexDir = IndexDir,
owners = Owner)
# after
buildRawRecordTable(path.records = RecordsDir, path.index = IndexDir,
owners = Owner)
buildRawIntensityTable(path.records = RecordsDir, path.index = IndexDir,
owners = Owner)Named callers must not keep recordsDir = or
indexDir =.
Single-path raw/archive helpers now use path:
archiveRawOwner(path = StationDir)
getRawIntensities(path = StationDir)
writeSelection(DT, name = "subset", path = SelectionDir)Named callers must not keep stationDir = or
selectionDir =.
parseRecord() and extractRecord() now
use .x for the one-record master subset and
path for the records root:
# before
parseRecord(masterRows = Rows, recordsDir = RecordsDir)
extractRecord(masterRows = Rows, recordsDir = RecordsDir)
# after
parseRecord(.x = Rows, path = RecordsDir)
extractRecord(.x = Rows, path = RecordsDir)Positional calls with both arguments, such as
extractRecord(Rows, RecordsDir), remain valid. Named
callers must not keep masterRows = or
recordsDir =.
auditParsers() now uses .x for the
master table, owner for one OwnerID, and path
for the records root:
# before
auditParsers(OwnerID = Owner, master = Master, recordsDir = RecordsDir)
# after
auditParsers(.x = Master, owner = Owner, path = RecordsDir)Named callers must not keep OwnerID =,
master =, or recordsDir =. Positional calls
must use the new order
auditParsers(Master, Owner, RecordsDir).
AT2TS(), VT2TS(), and
DT2TS() now expose time as an input-column
selector and always return canonical TSL columns
t, s, ID, and OCID.
The old COL.t and COL.s arguments are removed.
time is not an output-column name; it is only the name of
the time column in the input table. Scripts should migrate as
follows:
# before
AT2TS(Wide, Units = "mm", COL.t = "time", COL.s = "signal",
Output = "TSL")
# after
AT2TS(Wide, units.source = "mm", time = "time", output = "TSL")Downstream code must consume the returned TSL as
t and s. For example,
.SDcols = c("time", "signal") should become
.SDcols = c("t", "s"). Calls that already used a column
named t and did not pass
COL.t/COL.s do not need a script
change.
The constructor family also normalizes the approved public
argument names: Units -> units.source,
TargetUnits -> units.target,
Output -> output, Verbose
-> verbose, Audit -> audit,
isRawData -> isRaw, Resample
-> resample, FlatZeros ->
flatZeros, TrimZeros ->
trimZeros, Detrend -> detrend,
and Regularize -> regularize.
VT2TS() and DT2TS() additionally use
Derivate -> derivate and
LowPass -> lowPass.
regularize() is no longer public API. Time-grid
regularization is handled inside AT2TS(),
VT2TS(), DT2TS(), TS2IMF(), and
TSL2PS() via the internal helper
.regularize(). External scripts should pass
time = "..." to the constructor when the input time column
is not named t; they should not call
regularize() directly.
setSTFT() is no longer public API. STFT strategy
selection is now the internal helper .setSTFT() used by
AT2TS(), VT2TS(), DT2TS(), and
auditSTFT(). External scripts should configure the public
constructors instead of calling the STFT strategy helper
directly.
mapComponents(DT, rotate = TRUE) maps one long
(t, OCID, s) record to canonical processed directions.
Provider channels remain in OCID, returned DIR
values are H1 / H2 / UP, and
attr(out, "componentMap") records the OCID to
DIR mapping. With rotate = TRUE, horizontal
samples are rotated to principal axes and
attr(out, "theta") stores the rotation angle.mapOCIDtoDir() remained exported and unchanged in
0.4.5. It was removed from the exported package surface in 0.4.6.extractRecord() and raw CSV/JSON writer contracts are
unchanged; raw products continue to preserve provider OCID
values.AT2TS(), VT2TS(), DT2TS(),
getIntensity() now require canonical base
values for Units and TargetUnits:
"mm", "cm", "m"
— valid for AT, VT, DT."g", "gal" — valid
for AT2TS() only.VT2TS() and DT2TS() reject
"g"/"gal" (an acceleration unit passed to a
velocity/displacement function is a category error).getIntensity() accepts length-base only
("mm"/"cm"/"m") for
Units and TargetUnits; the same scale factor
applies to AT, VT, and DT rows of a long TSL, so only a length base is
well-defined."mm/s", "mm/s2",
"m/s2", "cm/s" are rejected with a clear error
pointing to the canonical base.KIND (acceleration / velocity / displacement) is determined by the
function called, not by a suffix of the Units string.
Provider string parsers .parseUnits() and
.parseKind() continue to accept heterogeneous raw strings
(e.g. "cm/sec2", "G", "GALS") —
those operate at the ingestion layer and pre-normalize to canonical
before flowing into the public API.
Migration: callers passing
Units = "mm/s" switch to Units = "mm"; same
for displacement. Callers passing Units = "g" to
VT2TS()/DT2TS() must move to
AT2TS().
Validated by a Ship-of-Theseus harness
(inst/dev/sot/compare_units_contract.R): Stage A 42/42
(canonical inputs byte-identical to prior gmsp via
identical()), Stage A-bis 3/3 (current verbose ≡ canonical,
documents migration), Stage C-bis 9/9 (illegal inputs error correctly).
Verify mode (post-swap-in, in-place edit vs captured baseline) 51/51
PASS.
readTS(SEL, recordsDir, kind) — canonical
KIND-parameterised sidecar reader. The previous readAT() is
now a one-line wrapper (kind = "AT"); the two new wrappers
readVT() and readDT() cover velocity and
displacement.readVT(), readDT() — thin wrappers around
readTS().readISEE() — Micromate ISEE blasting-seismograph parser
(velocity, mm/s). Auto-detects v10 / .TXT and v11 /
.CSV firmware variants from the file content.extractRecord() — KIND is routed through the sidecar
filename prefix (AT / VT / DT).
The JSON peak field is named accordingly: PGA /
PGV / PGD. An explicit
kind = "VT" override is accepted for records whose
Units cannot be parsed by .parseKind().buildRawRecordTable() — scans
raw/(AT|VT|DT).*.json (no KIND change to the canonical
schema).extractRecord() — full numeric precision preserved in
the sidecar JSON (no digits truncation).extractRecord() / getRawIntensities() —
raw CSV columns now consistently remain provider OCID
values while the JSON sidecar carries the explicit DIR
(H1/H2/UP) to OCID
mapping used by raw intensity indexing.TS2PS() — rejects user-supplied Tn grids
containing 0; the function already prepends the
Tn = 0 peak-value anchor internally.TS2PS(COL.ID = ...) — structured long input now treats
source time-series ID and spectral ID as
distinct contracts: AT -> PSA,
VT -> PSV, and DT -> SD.TS2PS(Output = "PSW") — multi-OCID long input now
produces wide OCID-labelled spectral columns such as
PSA.H1, PSV.H1, and SD.H1 instead
of source-ID-labelled spectral columns. Grouped PSW assembly no longer
uses rbindlist(fill = TRUE).TS2PS(D50 = TRUE) — structured long input can now add
OCID = "D50" as the fourth horizontal spectral component.
PSA.D50, PSV.D50, and SD.D50 are
computed independently from rotated AT, VT, and DT respectively.
TS2PS(D50 = TRUE) is the public D50 path.TS2IMF() — numeric imf.remove now treats
positive indices as IMFs counted from the start and negative indices as
IMFs counted from the end, then removes the union. For example,
c(1L, -1L, -2L) removes IMF1 plus the last two
IMFs. This replaces the previous positive-include / negative-protect
behavior, which made mixed selections such as c(1L, -1L)
remove nothing. Zero, non-finite, and out-of-range numeric values are
ignored.TS2IMF() grouped output no longer pads inconsistent
per-group schemas with NA. Groups must produce the same
output columns, or the bind fails with a schema diagnostic instead of
using rbindlist(fill = TRUE).AT2TS(), VT2TS(), and DT2TS()
no longer use blind na.omit() for time-step extraction or
TSL packing. Non-finite time and signal samples now fail with explicit
diagnostics instead of being hidden by regularization or row dropping;
finite regular and irregular inputs are unchanged.getIntensity() no longer uses
rbindlist(fill = TRUE) for the final
acceleration/velocity/displacement IM bind. Internal IM schemas must
match before binding.buildRawIntensityTable() no longer uses
fill = TRUE when binding new per-station intensity tables
or when merging an incremental cache. Raw intensity tables are
canonicalized and schema-checked before binding.buildRawFileTable() no longer uses
rbindlist(fill = TRUE). Provider records are canonicalized
to the documented RawFileTable schema before binding; absent canonical
provider fields are emitted as typed NA columns.buildMaster() no longer uses
rbindlist(fill = TRUE) across owner outputs. Per-owner
master tables must share the same schema before binding.wideTrunc() was removed. It had no internal callers and
no detected callers in the checked consumer projects
(AR-S2J2J, AR-SABP0.R).AT2TS(), VT2TS(), DT2TS(),
auditSTFT(), and .ffilter() without changing
public interfaces. The internal source file R/build_FFT.R
is now R/buildFFT.R..setSTFT() is tracked separately under Tier 2 SoT. The
approved passes remove a dotted boolean local, canonicalize the
candidate-logging guard, and inline a short-lived downsample scalar. A
later narrow local cleanup removes one-use k.grid, inlines
the one-use NP.required threshold, and resolves
NW.max / NWmax without changing
candidate/frequency locals. These changes do not alter the STFT strategy
or public interfaces.vignettes/database.Rmd — documents the
readTS() family and adds the ISEE blasting flow

Required paths. parseRecord(),
extractRecord(), buildRawFileTable(),
buildRawRecordTable(),
buildRawIntensityTable(), buildMaster(),
auditParsers(), writeSelection() and
readAT() no longer carry hard-coded
~/kashimaDB/... defaults for their path arguments
(recordsDir / indexDir /
selectionDir). The path is now a required argument; the
function fails fast with a clear “argument … is missing” error if not
supplied, rather than silently reading from a developer-specific
location.
Validated end-to-end by a Ship-of-Theseus harness: Stage A (explicit-path identity) 16/16 across 4 real provider fixtures (IGP, NGAW, NWZ, UCR); Stage A-bis (no-arg corner-case errors) 10/10. Pipeline regression 22/22 against the Phase 1 baseline.
readAT() signature. Now
readAT(SEL, recordsDir); previously read from the
unexported package constant RECORDS, which has been
removed.
Removed fossil parameters. Two parameters that were exposed in the public signature but never reached the function body are dropped:
AT2TS(..., Derivate = "time") — the source marked it
(future use); no caller used a non-default value and the
body never branched on it.TS2IMF(..., TrimZeros = FALSE) — the worker’s
if (TrimZeros) block was an explicit no-op
placeholder.Callers that passed either argument explicitly (none observed in the
gmsp ecosystem) will now get unused argument. The default
behaviour is unchanged.
