Hi everyone,

This is a short announcement for the users of ggplot and reshape.  I
have just released new versions of each that fix bugs when used with R

 * reshape was having problems with missing combinations of variables
 * errorbars in ggplot weren't working.

I've you've been having problems with either of these, please upgrade.

About ggplot

An implementation of the grammar of graphics in R.

ggplot is an implementation of the grammar of graphics in R. It
combines the advantages of both base and lattice graphics:
conditioning and shared axes are handled automatically, while
maintaining the ability to build up a plot step by step from multiple
data sources. It also implements a more sophisticated multidimensional
conditioning system and a consistent interface to map data to
aesthetic attributes.

About reshape

Reshape is an R package for flexibly restructuring and aggregating
data. It is available on all platforms supported by R (Linux, OS X,
Windows, ...).  Reshape (hopefully) makes it easy to do what you have
been struggling to do with tapply, by, aggregate, xtabs, apply and
summarise. It is also useful for getting your data into the correct
structure for lattice or ggplot plots.
