Anyone has some clue to this question?
Thanks in advance!

  You neglected to say that you were using the plotCI from gplots (not the
one from plotrix, which has slightly different behaviors).  Here's my
solution (with some data made up -- you didn't give a reproducible example).
I assume that you meant above that you wanted the line connecting the
centers to be dashed?

mcra1avg <- 1:3
stdev1 <- c(0.2,0.1,0.4)
plotCI(x=mcra1avg, uiw=stdev1, type="p",col=2,lty=2)

  By the way, it's not all uncommon to have to wait more than 12 hours for a
response on the R list -- the variability is very high ... I would say it's
generally good to wait at least 24 hours before "bumping" ...
