[R] the title is too long for a graph

[Greg Snow]

Here is one approach:

> tmp <- "p=0.05:A-B=3,C-D=10,D-E=100,A-F=2,AFR-E=3,ACE-D=1,ADEF-M=0,AED-E=10,DE-F=3,AB-J=4,AC-J=10,ED-F=1,ED-B=4,AF-B=10,CD-S=10,AM-C=4"
> tmp2 <- gsub(',',', ',tmp)
> tmp3 <- strwrap(tmp2, 30)
> par(mar=c(5,4,10,1)+.1)
> plot(1:10, main=paste(tmp3, collapse="\n"))

Hope this helps,
