There certainly is.  You can use a site profile file, or you can set
R_DEFAULT_PACKAGES.  Both are described in ?Startup (a pretty obvious
place to look, surely).  For example, you might put in 
R_HOME/etc/Rprofile.site

options(defaultPackages=c(getOption("defaultPackages"), "foreign", "survival"))
