Since many office PC's are centrally administed, user often have no permission to install R package to the default location of the R library. However, you can still install it on your own private library. For example: (inside R) > install.packages("dblcens", lib="C:/local/R2.7.1/library") You should create those directory first, and have write privilege. After install, load package by > library(dblcens, lib.loc="C:/local/R2.7.1/library")
