Hi,

I update R from 2.10 to 2.13.

Then I find soma problems when I start R.

Warning infos as below:

#####

  path[1]="": No such file or directory

I would guess you have something in an Rprofile or Rprofile.site file 
that is causing the error.  See ?Startup for the rules on where R looks 
for those files, and the other things that happen during startup that 
might be causing this.

Looks like it originates from a .libPaths() call, cf.
> .libPaths
function (new)
{
    if (!missing(new)) {
        new <- Sys.glob(path.expand(new))
        paths <- unique(normalizePath(c(new, .Library.site, .Library),
            "/"))
        .lib.loc <<- paths[file.info(paths)$isdir %in% TRUE]
    }
    else .lib.loc
}

maybe something wrong with your R_LIBS(it should be "R_LIBS=dir/R-
3.0.0/lib64/")
