Overview

About

Maintained by Kyun-Seop BaeCRAN page ↗

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: no external toolchain is started and the document is written in a single pass. Interactive AcroForm CRFs are out of scope.

Changes in 0.1.2

Bug fix release.

Fixed a crash in the flow engine when a block's height equalled the space left on the page to within floating-point error: split() then reported the whole block as fitting (head = <block>, tail = NULL) and .place_block() went on to measure the NULL tail ("attempt to apply non-function"). .place_block() now (a) treats a block as fitting when its height exceeds the remaining space by less than 1e-9 pt, matching the tolerance the split() methods already use, and (b) stops cleanly when a split returns no tail, instead of starting a page for it. Affected block_para(), block_pre() and block_table() alike; nmw worked around it. Regression-tested in inst/tinytest/test_flow.R.
.block_seq() (used by block_table()/block_matrix()) now returns tail = NULL rather than an empty sequence block when a split consumes every sub-block, which also removes a spurious trailing blank page.

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("simPDF", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-simpdf

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-simPDF

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-simPDF

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
