[R] update R packages in local repos

[Muhammad Subianto]

I try to update R packages via my local repository.
I put all R packages in g:/myFolder/myRepository, I do like

> library(tools)
> write_PACKAGES("g:/myFolder/myRepository")
> options(repos=c(LocalR="file://g:/myFolder/myRepository"))
> getOption("repos")
                           LocalR
"file://g:/myFolder/myRepository"
> update.packages(ask = "graphics")
Error in gzfile(file, "r") : unable to open connection
In addition: Warning message:
cannot open compressed file
':/myFolder/myRepository/bin/windows/contrib/2.2/PACKAGES'
>
> ?update.packages

It produces these file in g:/myFolder/myRepository
PACKAGES
PACKAGES.gz

Could I make this folder (bin/windows/contrib/2.2/)? Why?
