R libraries installation

I am using a computer where I have read only rights for the R library folder. When I am installing new packages I therefore use

libpath <- "c:/R/mylibraries"
.libPaths( c( .libPaths(), libpath) )
install.packages("htmltools",   lib=libpath)

always when I am installing a new packages with dependecies (like e.g. htmltools depends on lme4), I get erros like:

Error in .requirePackage(package) : 
  unable to find required package ‘lme4’

although lme4 is installed and I used it before.... also other errors/warnings like:

Warning in install.packages :
  cannot remove prior installation of package ‘Rcpp’

or:

Warning in install.packages :
  unable to move temporary installation ‘c:\...\file17b033a54a21\jsonlite’ to ‘c:\...\jsonlite’

occur. If I install them twice they usually work but sometimes dependencies to packages that worked before are lost and I have to reinstall them again. Is there a way to circumvent this?

Put this in a file named .REnviron in your Documents folder and restart R:

R_LIBS=c:/R/mylibraries

From then on, you should be able to install packages into that location automatically, without having to fiddle around with .libPaths.
