Hello List,
I'm building a package for R, and I want to use the font family
'symbol', because it seems to be the most consistent of the four font
families that par guarantees. The problem is that when I tried to run
it on a different machine, I got an X11 error message saying that that
font family was not available.
What I would like to do, therefore, is do a check at the beginning of
the programs to check if the 'symbol' family will work, and use the
default font family if it will not. I figured I could do it with
either require() or tryCatch() but I can't seem to get either of them
to do it. If anyone has any idea how to check for the presence of
font families could they please let me know?
#####Sample code
if(HERE IS WHERE THE CHECK FOR 'symbol' WOULD GO){
fam = 'symbol'
}
else{
fam = ''
}
par(family=fam)
#####
Thanks,
Sam
