Thanks for the help Jim,
The legend function solved the legend border problem but the labels, even
using staxlab from plotrix are still being cut by the device limits, like
there is some kind of character number limits or something like that.
Anyway thank you so much, I'll keep trying and searching.
Rodrigo.

Hi everybody,
well I'm trying to use barplot for the first time. I get a suitable
graphic but I'm having a weird problem.
My graphic is generated from a matrix with several species (rowNames) and
two abundance columns.
So each species will have two bars, and the species name should appear at
left. Until now everything is Ok, but when a I plot it the species names
(my labels) are cut by device limits, and only part of the names appear.
I could move them with the command "line=some negative value", but the
axis (x and y) stay put and the things get over each other (the command
'line' works, but a error saying that it's not a graphic parameter
appears). In addition, but with less importance, how could I remove the
legend borders? And why, when I try use the 'width' command it fails to
raise the width of the bars and I get and error saying that its not a
graphic parameter (the command is in barplot help!!)?
I'm using R 2.8.0 at Windows XP 32 bits.
Here is the code I'm using, where MainSpp is my matrix:
barplot(MainSpp,horiz=T,beside=T,main='Main Species',xlab='%',las=1,
legend.text=T,width=5,cex.names=0.8)
Hi Rodrigo,
I think that the function in the plotrix package might do what you want.
For the legend problem, I would suggest not using the barplot legend
option but using the legend function with bty="n".
Jim
