crs

This is the R package `crs’ (Categorical Regression Splines) written and maintained by Jeffrey S. Racine (racinej@mcmaster.ca) with the invaluable assistance of Zhenghua Nie.

Installation

You can install the stable version on CRAN:

install.packages('crs', dependencies = TRUE)

Or download the zip ball or tar ball, decompress and run R CMD INSTALL on it, or install then use the devtools package to install the development version:

library(devtools); install_github('R-Package-crs', 'JeffreyRacine')

Note Windows users have to first install Rtools, while OS X users have to first install Xcode and the command line tools (in OS X 10.9 or higher, once you have Xcode installed, open a terminal and run xcode-select –install).

Release Validation

CRAN-ready release claims should use the shared release gate:

cd /Users/jracine/Development
./release_protocol/run_crs_release_gate.sh

The gate builds the source tarball, installs it into a private library, runs installed smoke tests, runs tarball-first R CMD check --as-cran, records reverse-dependency inventory, and runs the containerized rchk native-code protection check when feasible (RUN_RCHK=auto by default).

For changes touching src/, NOMAD interface code, registered native interfaces, or .C/.Call payload lifetimes, require local rchk proof when infrastructure is available:

cd /Users/jracine/Development
RUN_RCHK=1 ./release_protocol/run_crs_release_gate.sh

Use RUN_RCHK=auto for ordinary full release rehearsal; it records a precise SKIP when Docker/rchk infrastructure is unavailable.
