Dear friends, I am having some doubts about the amount of memory that is being used by R in my Mac (MacBook Pro, 2Gig). Is there a way to increase the amount of memory used?

Hi, I have been asked by a publisher to change the font style of a lattice plot in my manuscript. I have consulted documentation on trellis graphics and the excellent book "R graphics", but am still not sure how I could create plots with Arial as the font style for text in the plot. I am running R (Version 2.3.1 (2006-06-01)) under debian Linux. I have msttcorefonts installed.
