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).

For more information on this project please visit the maintainer’s website (https://www.socialsciences.mcmaster.ca/people/racinej).

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.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
