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 can use ggplot2 to rotate the x-axis label adding an additional layer

theme(axis.text.x = element_text(angle = 90, hjust = 1))
