[R] dotchart to barplots

[Nair, Murlidharan T]

Ok, I could make it perpendicular by specifying las=2

barplot(t(as.matrix(intersect.data[,2:5])),
          beside = T, horiz = T,
          names.arg = intersect.data[,1], cex.axis = 0.7, cex.names = 0.7, las=2)

Still working on the other though. 
Cheers../Murli

I had tried names.arg=c(intersect.data[,1]) so that was the problem. That solves part of what need. I there a way to rotate how it is written on the y-axis?  Also, use designs instead of gray scale and making keys for it?
Thanks for chipping in.
Cheers../Murli

Try this:

barplot(t(as.matrix(intersect.data[,2:5])),
          beside = T, horiz = T,
          names.arg = intersect.data[,1], cex.axis = 0.7, cex.names = 0.7)

Is there a way to give the labels for the y-axis as in the dot chart? Also, I feel the grey level is confusing, so is there options for designs within the bars? I cannot use color as the journal wants it in black and white.  I also need to specify the key. If someone has done it, I would appreciate your input.
