I have been able to solve my problem. Please don’t bother. Thanks

Dear All,

I have been able to make a grouped panel bar plot (please see attached), I
am however trying to add error bars to one of the bar plots (ERA-interim)
across the panel and failing.

I am able to do that for just the first marplot, but my loop to apply to
the others is failing. Here’s a snippet of my code and I will be grateful
for any help. The snippet below shows what I have tried to do to apply to
panels 2:4.

postscript(“test.eps",width=10,height=8,paper="special",horizontal=T,onefile=T)

par(mfrow=c(3,4))
#par(mar=c(8.8,3.5,1.0,0), oma = c(4, 4, 3, 3)) # spaces in the order of
c(bottom,left,top,right)
par(mar=c(6,7,1,1))

Any help will be much appreciated.
