Hi,
I'm attempting to make a bar plot for some genomics data that includes
a separate bar for each sample taken. I am having trouble applying these sample
labels to the individual bars. It seems that the barplot() function will only
take a numeric matrix, and therefore cannot have any character vectors
included. Thus, I can make a bar plot that labels the bars 1,2,3,etc., but not
with the actual sample names. Any help would be appreciated.
Hi Alexander,
As Sarah pointed out, the names.arg= argument allows you to pass labels
for the bars. As the labels are often sufficiently long that only some
will be displayed, it might be worth looking at the staxlab function in
the plotrix package if you have to display all of the labels.
