[R] Boxplot names

[Bert Gunter]

You might alternatively find the horizontal = TRUE with las=2 to be useful; e.g.

dat <- data.frame(val=rnorm(100),
  grp=rep(apply(matrix(sample(letters,100,rep=TRUE),nr=5),2,paste,collapse=""),5))

boxplot(val~grp,horizontal=TRUE,data=dat,las=2)

## Note that las=2 might also help with horizontal=FALSE, but I prefer
reading Roman language labels horizontally. CJK languages might prefer
vertically.
