"R (The R Project for Statistical Computing)"
"R is a language and environment for statistical computing and"
"graphics. It is a GNU project which is similar to the S language and"
"environment. The S language is often the vehicle of choice for"
"research in statistical methodology, and R provides an Open Source"
"route to participation in that activity. One of R's strengths is the"
"ease with which well-designed publication-quality plots can be"
"produced, including mathematical symbols and formulae where needed."
