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 staxlab 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".
