Hello there, I would like to produce a plot of x<-c(4,5,6),which is the mean of each group and y<-c('groupA','groupB','groupC').
plot (x,y) can not produce any graphics because y is not numerical. What should I do to produce this graphic? Thank you in advance Lisa Wang Princess Margaret Hospital Toronto,Ca ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
