Fast Multi-Page PDF Report Layout on the Graphics Device R package simPDF version 0.1.1 A lightweight, dependency-free engine to build multi-page PDF reports quickly on top of R's built-in graphics device ('pdf'/'cairo_pdf'). Content is placed by a measured flow layout: every text block reports its real width and height via 'strwidth'/'strheight', the vertical cursor advances by measured height, and pages break automatically. This eliminates the text-overlap of dead-reckoned coordinate reports (such as the 'nmw' NONMEM diagnostic reports) and replaces slow '.Rmd'/'knitr'/'LaTeX' pipelines for fixed report generation. Interactive AcroForm CRFs are out of scope and handled by the sibling 'pdfCRF' package. Software Depends: R (>= 3.6.0) Imports: grDevices, graphics Suggests: tinytest, png, jpeg, knitr, rmarkdown Kyun-Seop Bae <k@acr.kr> Comprehensive R Archive Network (CRAN) Kyun-Seop Bae [aut, cre] GPL-3 2026-07-30 application/tgz https://CRAN.R-project.org/package=simPDF doi:10.32614/CRAN.package.simPDF
