Name        : R
Product     : Fedora 15
Version     : 2.12.2
Release     : 1.fc15
URL         : http://www.r-project.org
Summary     : A language for data analysis and graphics
Description :
This is a metapackage that provides both core R userspace and
all R development components.

R is a language and environment for statistical computing and graphics.
R is similar to the award-winning S system, which was developed at
Bell Laboratories by John Chambers et al. It provides a wide
variety of statistical and graphical techniques (linear and
nonlinear modelling, statistical tests, time series analysis,
classification, clustering, ...).

R is designed as a true computer language with control-flow
constructions for iteration and alternation, and it allows users to
add additional functionality by defining new functions. For
computationally intensive tasks, C, C++ and Fortran code can be linked
and called at run time.

Update Information:

Update to R 2.12.2. A full list of changes in this release is here: http://cran.r-project.org/src/base/NEWS

Notably, it fixes this issue:

Complex arithmetic (notably z^n for complex z and integer n) gave
incorrect results since R 2.10.0 on platforms without C99 complex
support. This and some lesser issues in trignometric functions
have been corrected. Such platforms were rare (we know of Cygwin and FreeBSD). However, because of new compiler optimizations in the way complex arguments are handled, the same code was selected on x86_64 Linux with gcc 4.5.x at the default -O2 optimization (but not at -O).

In addition, rpy and rkward were rebuilt to use the new R. No other changes were made to these packages.

This update can be installed with the "yum" update program.  Use 
su -c 'yum update R' at the command line.
