[R] dotchart to barplots

[Peter Ehlers]

Murli,

Two points:
1. I think you might want las=1;
2. have a look at the density= argument,
i.e. add density=c(10,20,30,40) to your call.

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.
