Hello there,

I have a question regarding bar plots. I am trying to plot the data from
the following matrix as a barplot -

# input data
mdat <- matrix(c(0.1,0.9,0.9,0.1,0.5,0.5,0.45,1-0.45,0.6,0.4,0.8,0.2), nrow
= 6, ncol=2, byrow=TRUE,
+                dimnames = list(c("Mon", "Mon", "Tues", "Tues", "Thurs",
"Friday"),
+                                c("C.1", "C.2")))

# plot

barplot(t(as.matrix(mdat)), col=rainbow(2), ylab="Sales", names.arg =
rownames(mdat), border=NA, cex.names=0.5)


I am using names.arg to print the label for the bars. However, I would like
to group all the entries for the Mon and print the label only once. Is
there a way to do this? The documentation for barplots suggests that this
can be done but I was not able to figure it out. Please help.


Thanks in advance,

Diviya
