R help - Jan 2012 - Rotated Labels for grouped bars

I want to create a barplot but need to rotate the labels:



a <- c(1,2,3,4) ; b <- c(2,3,4,5);  c <- c("Loblolly Pine",
"Oak Hickory",
"Sweetgum", "Tulip Poplar")

d = rbind (a,b)

bar <- barplot(d , beside=TRUE)

text(bar, par("usr")[3]-.0025,srt=45,adj=1,labels=c,xpd=TRUE)



I cannot figure out how to get the rotated labels to match up with grouped
bars rather than individual bars - ie one label per group



Cheers,



Jim

Change to
text(colMeans(bar),
par("usr")[3]-.0025,srt=45,adj=1,labels=c,xpd=TRUE)
