Dear SavioRs,

I am doing some research where characters in different microsoft fonts serve as experimental stimuli. Hence, in plot labels, I would like to display the characters in specific microsoft fonts. I have figured out how to display letters and numbers, but I am having trouble with symbols such as capital delta. Before I go further, I am using R 2.2.1 on Windows XP with everything in English. I am trying to save my plot as a windows metafile.

To display different characters in verdana, for example, I first edit the Rdevga file so that it contains verdana. I can then get verdana letters and numbers on the plot using a text() command. Things within an expression() command, however, are not displayed in the desired font. For example,


displays a capital delta, but it is not in font #10 within Rdevga. I can get characters that have one of the first 255 ascii codes using chars8bit() in the sfsmisc package. One example is the division sign:


I have not been able to display other symbols in microsoft fonts, however. Is this possible to do in R? All replies are appreciated.
