Hi,
May be:

barplot(m$V3,names.arg=paste(m$V2,m$V1,sep="\n"),col=rainbow(10))
#or
barplot(m$V3,names.arg=m$V2,col=rainbow(20),legend=m$V1, args.legend = list(x = "topright",box.lwd=0,border=FALSE))

as you can see, the table is sorted by the second and the first column.
with this command :
barplot(m$V3,names.arg=m$V2,col=rainbow(10))
I succeded to print the figure attached.
Now, I need to indicate that the first 10 bar are for beta=0 and the second
10 bars are for beta=1.
Could you help please.
Best regards
