Plenty. See the examples vignette for a full set of introductory examples. Also see the examples/ directory for a full 28 example scripts, as well as maybe the older tests directory both of which are installed with the package.
Some scripts I uses daily or near daily (in alphabetical order):
build.r ## builds from the current directory c4c.r ## submits current directory to winbuilder compAttr.r ## run compileAttributes() for a Rcpp package dratInstert.r 1.2-3.tar.gz -r /srv ## inserts package into drat repo install.r abc def ## installs packages abc and def install.r abc_1.2-3.tar.gz ## installs given tarball install2.r -l /tmp/lib abc def ## installs abc and def into /tmp/lib rcc.r abc_1.2-3.tar.gz ## run's R CMD check via Gabor's rcmdcheck render.r foo.Rmd ## calls rmarkdown::render() roxy.r ## run roxyenize() for a package (only Rd creation) update.r ## updates any currently installed packages
The package resides on the CRAN network and can be installed via
In general, simply running the script
bootstrap will configure and build the executable. Running
make install (possibly as
sudo make install) will install the resulting binary.
On Linux systems, ensure you have the
autotools-dev package (or its equivalent on non-Debian/Ubuntu systems). On OS X, you may need to run
brew install automake autoconf to get all the tools.
On some operating systems such as OS X,
r is not different from
R. As this risk confusing the main binary
R for the R system with our smaller scripting frontend
r, we suggest to consider running
configure --program-prefix="l" which this leads to installation of a binary
lr instead of
As littler uses autoconf its
AC_PATH_PROG() macro to find
R, one can simply adjust the
PATH when calling
configure (or, rather,
bootstrap) to have another version of R used. For example, on a server with R-devel in this location, the following builds littler using this R-devel version:
