R: How can I make a barplot with labels parallel (horizontal) to bars

Question

In barplot, is it possible to make the labels parallel to the bars?

Suppose we have the data frame called \"data\".

              Page   PV UniquePgv
1 /         


        

Answer 1

You can use the las graphics parameter. However, if you do that, the names will run off the end of the window, so you need to change the margins. For example:

par(mai=c(1,2,1,1))
barplot(data$PV,main="Page Views", horiz=TRUE,names.arg=names,las=1)
