 
I am having problem installing the package: R.classes
Which contains package R.oo
which is needed to run function robustPca
 
How can I download package R.classes?
It is supposed to be "100%R"
 
I have R version 2.7.2
 
 
 
 
History:
I followed the instructions/vignette for using pcaMethods package
when I attempted the robustPCA function, as in 
 
resRobSvd<-pca(mdcOut,method = "robustPca", nPcs = 5, center = FALSE)
 
I received an error message requesting loading of aroma.light package.
 
I loaded this package
 
Then I received an error message requesting loading of R.oo package.
R.oo package not on the Bioconductor site.
I searched Google and found R.oo package part of R.classes package, and
is "100%R"
I searched the Bioconductor site and could not find package R.classes
I Googled R.classes and first entry instructed me to use function
install.package()
install.packages("R.classes",contriburl="http://www.maths.lth.se/help/R/
R.classes/")
got error message: subscript out of bounds
