Dear sir,
I tried "help.search("rnorm")" in R version 3.1.2 .
It gave a error
"Error in `[<-`(`*tmp*`, , "name", value = sub("\\.[^.]*$", "",
basename(vDB$File))) :
subscript out of bounds".
Can you tell me the reason.It may be silly.

Re: [R] Installing RStudio
Dear John,
I think you have to specify the directory of R in the R-studio installation
process. Somehow the installation wizard is unable to find the address of R
in your system.
