I am getting the following error in my script. I am very very new to R and have obtained this script from another person. #read file in (dummy data) starburst.plot<-function(affy.fold, affy.FDR)(ifelse( ((affy.fold) >=0), -1*log10(affy.FDR), 1*log10(affy.FDR))) starburst.plot<-function(meth.fold, meth.FDR)(ifelse( ((meth.fold) >=0), -1*log10(meth.FDR), 1*log10(affy.FDR))) At my next

...pretty good polygon hatching algorithm written and running in R. It's robust when implemented in floating point arithmetic, runs in time at worst linear in the diameter of the area and O(n log n) in the number of sides of the polygon, and works well on my ugly testcases (like 500-point random starbursts, self-intersecting polygons, and so on). I don't expect any difficulty in implementing it as a part of R's "graphics.c". Unless your student is really, really excited about polygon hatching (and who wouldn't be!), maybe there's something else you want to force him or her...
