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")


What if you do not have R itself and are not allowed to install it?
(due to admin permission etc)

Well, then you may install a version of R that is called "Portable R".
A portable version of software can be installed on a USB drive
(for example) and can also be installed on the user directory of
the computer. Google portable R.
