What is R
R is a free software environment for statistical computing and graphics. It is used in academia and industry, in many different fields, from (obviously) statistics, finance, high-thoughput biology (omics), … and can be expanded at infinity through package (CRAN, Bioconductor, R-Forge, omegahat).
The are vast amounts of documentation about R: - the R manuals page edited by the R Development Core Team - each function has it own manual page and some packages come with a global overview in the form of a vignette - many free documents and tutorials freely available - lots of general or specialised books - several mailing lists and dedicated QA sites - … - … - and this little collection of tips and tricks that I found useful to collect.
Before setting up to repository, the content was available on slashhome.be. The publication date is when the content was moved here; some posts are much older and possibly a bit outdated.
