characterTable <-
function(font = 1, cex = 0.7)
{
# A function implemented by Diethelm Wuertz
# Description:
# Prints numeric equivalents to all latin characters.
# Notes:
# The printed version doesn't allways corresponds to the
# screen display. The character on line "xy" and column
# "z" of the table has code "xyz". These codes can be
# used as any other characters.
# e.g. title("\347\340 et \340")
# Note on S:
# As the command line window of Splus can't print special
# characters
# cat("\347\340 et \340")
# will not print the special characters, at least under
# 4.5 and under 2000.

# FUNCTION:
# Table:
v = 40:377
v = v[v %% 100 < 80 & v %% 10 < 8]
