and ../ihsMW-user-guide.Rmd) in the
getting-started and ihsMW-user-guide vignettes
with absolute URLs to the package website. The relative form resolved
correctly on the pkgdown site but pointed outside the package when the
vignettes were installed to inst/doc/, which CRAN’s
incoming checks flagged. No user-facing behaviour changes.Version 1.1.0 was not released; see its entry below for the substantive changes, all of which are included here.
ihs_harmonise(),
ihs_search(), ihs_panel_ids(),
ihs_deflate(), ihs_crosswalk_check() and
check_round().ihs6_name column with
3,214 IHS6 variables, built from the official IHS6 data
dictionaries rather than inferred. 2,561 map onto existing harmonised
variables and 653 are new in IHS6, of which 632 are flagged
needs_review (see below). The crosswalk now holds 6,482
variables.ihs_panel_ids("IHS6") records the design stratum rename
from stratum to strata.
ihs_svydesign() already detected both, so survey designs
build unchanged on IHS6 data.ihs_deflate() maps IHS6 to its 2024 survey midpoint
year.ihs_deflate() scales every monetary variable by
base_cpi / round_cpi, that error propagated into every
real-terms figure the package produced. The table is now derived from
World Bank WDI FP.CPI.TOTL rebased to 2019 = 100, covering
2004-2025, and is regenerated by data-raw/02_build_cpi.R.
Deflated values will change.n_rounds column was
stale for 5,779 of 5,829 rows (99.1%), claiming 4-round
coverage for nearly every variable when only 50 appear in all of
IHS2-IHS5. ihs_search() displays and sorts by this column,
so search results systematically misreported cross-round availability.
It is now recomputed from the round-name columns.NA. ihs_convert_units() now applies the
identity, recovering 506 rows (5.3%) across the IHS6 harvest and sales
modules. The rule is derived from the bundled table, not
hard-coded: if a future NSO release gives the kilogram unit a
crop-specific factor, it switches itself off.ihs6_expansion_of. IHS6 is collected in Survey
Solutions, which splits a “select all that apply” question into one
binary column per option - IHS5’s single ag_e07 becomes
ag_e07__1, ag_e07__4 and so on. 342 IHS6
columns are such expansions. They are now labelled with their parent
question instead of being lumped into needs_review, which
drops from 653 to 632 and, more importantly, now means something
specific: new in IHS6 and not cross-checked against an earlier
instrument. ihs_search() returns the column and
ihs_crosswalk_check() reports it.mw_cpi_annual.csv
gains retrieved and provisional columns. The
World Bank revises recent observations, so the two most recent years are
flagged, and ihs_deflate() says so when a round you are
deflating depends on one - as IHS6 (2024) currently does.ihs_harmonise() could rename the same raw column twice
when two crosswalk entries differed only in letter case, silently
overwriting the first harmonised name and then failing with “Can’t
subset columns that don’t exist”. Each raw column is now claimed by at
most one crosswalk entry.ihs_convert_units() returned a silent
all-NA column when the crop or unit column contained value
labels instead of numeric codes - the case for some IHS CSV
distributions, including IHS5. It now fails with an explanatory error
naming the offending values and pointing at the .dta
distribution.ihs_merge() no longer warns about row growth on a
type = "full" join, where more rows than either input is
the expected result.ihs_merge() now warns when columns present in more than
one input are given .x/.y suffixes. This
silently breaks downstream auto-detection: once hh_wgt
becomes hh_wgt.x, ihs_svydesign() can no
longer find the survey weight.ihs_deflate() now validates the ihs_round
column up front, so an unrecognised round produces an actionable message
instead of a “subscript out of bounds” error.ihs_convert_units() is 5.2x faster
(1.51 s to 0.29 s on 99,988 crop records). The row-by-row factor lookup
was replaced with a vectorised one; output is bit-for-bit identical,
verified across IHS4, IHS5 and IHS6 agriculture modules.ihs_clean(missing_cols=, winsorize_cols=, strata_col=),
ihs_winsorize(value_col=, strata_col=),
ihs_convert_units(region_col=) and
ihs_aggregate(id_cols=, val_cols=). Every documented
example now runs as written.ihs_clean(),
