[R] Question on qplot

[RON70]

I have updated the ggplot2 package as well as R, how got some new error.

> qplot(x, z) 
Error in get("new", env = FacetGrid, inherits = TRUE)(FacetGrid, ...) : 
  could not find function "is.formula"

I cannot understand what is happening with my system. Here I am providing
the details of my system and package:

> packageDescription("ggplot2")$Version
[1] "0.8.2"

> R.version.string
[1] "R version 2.9.1 (2009-06-26)"

I am using windows vista (build 6002, Service Pack 2).

Please help.

Thanks
