R help - Sep 2008 - boxplot labelling levels

I want the levels to appear in  the boxplot instead of 1 and 2. What do I need
to do for that?  Here is the dummy code.


x<-runif(100,50,80)
x1<-runif(100,70,80)
True.positives<-c(x,x1)
splice<-factor(c(rep("Human.AA.200",100),rep("Human.AA.100",100)))
splice<-factor(splice,levels=c("Human.AA.200","Human.AA.100"))
svm.perf<-as.data.frame(cbind(True.positives,splice))
boxplot(True.positives~splice,data=svm.perf, ylab="True positives")

Dear Murlidharan,
See argument 'names' in ?boxplot. In your case, it is:

boxplot(True.positives~splice,data=svm.perf, ylab="True
positives",names=levels(splice))


HTH,

Jorge
