Rotating x axis labels in R for barplot

Question

I am trying to get the x axis labels to be rotated 45 degrees on a barplot with no luck. This is the code I have below:

barplot(((data1[,1] - average)/averag         


        

Answer 1

You may use

par(las=2) # make label text perpendicular to axis
