As I said this works great - but now I would like to use the table
heading as legend - and have no idea how to access the header (see below)

Subject: [R] Matrix barplot
Year A B C
2000 4 3 0
2001 2 1 3
2002 1 2 5
What do I need to specify as legend.text in the barplot command
to get A / B / C in the legend if I read the file using
data <- read.table(file='data.dat', sep = '\t', fill=TRUE, header=TRUE )
Kind regards
Andreas.
