Hi,
I have been using R to create some mathematical and statistical graphs for a book manuscript, but I got some problems:
1) Some web positngs said that default typeface for math expressions is italic, but in my system (R 2.01 on WinXP), the default is regular font.
How can I change the default to ilatic?
expression(italic(whatever))
2) When use ComputerModern font, (i.e., family=c("CM_regular_10.afm","CM_boldx_10.afm","cmti10.afm","cmbxti10.afm","CM_symbol_10.afm") ), some accented symbols are not available. For example, "expression(hat(beta))" will produce warning message like "font metrics unknown for character 94."
That appears to be a bug (that requires changes to the PostScript device driver). A nastyish workaround for hat(beta) is widehat(beta), but I suspect there are other problems that this will not solve.
