### Bug-tracking system

R has a bug-tracking system (or perhaps a bug-filing system is a more precise description) available on the net at

> http://bugs.r-project.org/

and via e-mail to r-bugs@r-project.org. The R function `bug.report()` can be used to invoke an editor from a within an R session and send the report to the right address. It also fills in some basic information, such as your R version and operating system, which has proved helpful in the debugging process.

The source distribution has a file `BUGS` at the top level giving a summary of the entries at the time this distribution was prepared.
