Dear R - users, I am interested in being able to generate simple network graphs (food webs, mostly) that have labels containing both greek letters (e.g. alpha) and subscripts (e.g. expression(alpha[ij]) ). I have been trying to accomplish this in Graphviz (Mac version by pixelglow) but cannot do it. I cannot seem to make the instructions at att.com for Graphviz work (using code of the characters). I have tried to get a Unix version going through Aquamacs and have GD libgd problems. I have searched the web for R-related solutions and noted that "gaggle" might be a possibility. -- What do other folks use? -- Any thoughts appreciated. I am using R version 2.4.0 (2006-10-03) on a Mac OS X, and yesterday's downloads of biocLite, Rgraphviz, and Graphviz.
