Hi: if you mean that you want the labels to be the strings "-1.55", "-1.50"
etc then you
can use the names.arg argument for that. You can create a vector of
character strings
binstrings = c("-1.55","-1.50", .... )
or just convert your data to strings using as.character. Then, in the call
to barplot, include names.arg = binstrings. I think that should work.
