[R] Font and Color documentation

[Iyue Sung]

Hello R-ians,

  Could someone please point me to documentation on legal font and color
specifications (and other 'par' parameters); i.e. font=6 for Times New
Roman, col='Red', etc.?  Searches in "?par", MASS (1st ed.) and other
areas were unsuccessful. I thought I remember seeing it
before...somewhere.

Thanks,
Iyue
