    and graphics. It is a GNU project which is similar to the S language \
    and environment which was developed at Bell Laboratories (formerly   \
    AT&T, now Lucent Technologies) by John Chambers and colleagues. R    \
    can be considered as a different implementation of S. There are      \
    some important differences, but much code written for S runs         \
    unaltered under R."
