[R] Question on qplot

[Gabor Grothendieck]

Although there is no explicit support for ggplot2 in zoo
currently (hopefully there will be in the future) both your
qplot commands do work for me using:

> packageDescription("ggplot2")$Version
[1] "0.8.3"
> packageDescription("zoo")$Version # devel version
[1] "1.6-0"
> R.version.string # Windows Vista
[1] "R version 2.9.1 Patched (2009-07-16 r48939)"

For the devel version of zoo see the installation instructions
at the bottom of::
