# Things you might want to change

# options(papersize="a4")

# options(editor="notepad")

# options(pager="internal")

# set the default help type

# options(help_type="text")

  options(help_type="html")

# set a site library

# .Library.site <- file.path(chartr("\\", "/", R.home()), "site-library")

# set a CRAN mirror

# local({r <- getOption("repos")

#       r["CRAN"] <- "http://my.local.cran"

#       options(repos=r)})

# Give a fortune cookie, but only to interactive sessions

# (This would need the fortunes package to be installed.)
