Is it possible?
I was hoping to find something like:
lwd
for the different bars in the barplot but couldn't find it.
Does it exist ?
Thanks,

barplot() calls rect() via a wrapper function internally to draw the
rectangles. rect() uses par("lwd") to define the line widths by default:
par(mfrow = c(2, 1))
barplot(1:5)
par(lwd = 3)
barplot(1:5)
If you wanted to define the widths of the lines on a per bar basis,
you would need to manually create the bars using rect() directly,
since there is no other way that I can see to pass a vector of line
widths as the code is presently implemented.
You might want to look at the barchart() function in lattice to see if
there is more functionality there.
