[BioC] error opening corPlot.R

[Swati Ranade]

Hi I am trying generate scatter plots using the
corPlot function in R and am getting the following
error:
> source("CorPlot.R")
Error in file(file, "r") : unable to open connection
In addition: Warning message: 
cannot open file `CorPlot.R' 

I use the 2.0 version of R. Can any body suggest how
to resolve this issue?

Thanks,

Swati
