Fast, base-R, multi-page PDF reports on the graphics device.
simPDF lays out reports on R’s built-in
pdf() / cairo_pdf() device with a
measured flowing layout: every block reports its real
width and height, the cursor advances by that measured height, and pages
break automatically. Text, tables and matrices therefore never
overlap, however many rows or parameters they contain — the
failure mode of reports built from hand-computed coordinates.
It is a fast, dependency-light alternative to
.Rmd/knitr/LaTeX for fixed-format
reports: no external toolchain, one write pass, base R only.
Interactive fillable forms (AcroForm CRFs) are out of scope and handled by the sibling package pdfCRF.

sp_new(),
frame_set(), flow_run(); blocks:
block_para (wrapped/aligned text), block_pre
(capture.output() dumps), block_table (auto
column widths, repeating header, page-splitting),
block_matrix (wide matrices split into column groups),
block_plot (inline plots), sp_figure_page()
(full-page multi-panel figures), block_image,
block_keep, block_spacer,
block_rule, running headers/footers.sp_width/sp_height) drives every placement;
sp_trace() / sp_overlaps() let you assert zero
overlap in tests.block_authorship() and
block_signature() draw a prepared-by block and approval
lines; sp_add_sig_fields() adds interactive Adobe Acrobat
signature fields (/Sig) to the finished PDF via a pure
base-R incremental update.block_flow_diagram() renders a tree of nodes as measured
boxes, scaled to fit the page.simPDF for its NONMEM
