[R] Boxplot function error-help required

[John Kane]

Well it might have worked for your supervisor but I don't see how.  

As was mentioned it is boxplot , not Boxplot and the rest of the syntax looks dodgy to say the least.

Try 
boxplot(Acc_S$Subj ~ Acc_S$Acc)

I don't see how label = will work , ?boxplot says it should be names = and as the code stands even that would be redundant.  

In any case here is a quick and dirty example that seems to work. 

 dat1  <-  data.frame(aa = sample(letters[1:4], 20, replace = TRUE), bb = rnorm(20), cc = rnorm(20) )
boxplot(dat1$bb~ dat1$aa, names = c("alpha", "beta", "gamma", "delta"))


Have a look at http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example and http://adv-r.had.co.nz/Reproducibility.html
 for some suggestions on how to ask questions here.

Good luck
