R help - Feb 2016 - R portable is unable to open base package

I'm using shiny package to make a desktop application for my GUI. When I run
my batch file, I receive the following error in the log file:
Fatal error : unable to open the base package

I checked my library path and it was correctly set to R portable library path.
Also I tried to install base package using install.packages("base")
but R gave a warning: package 'base' is not available (for version R
3.2.3)

How should I solve this problem?
