Yes, you say "axes=F" in the initial plot, then you can put labels
anywhere with any strings at all, in a call to axis().

For example:

x <- runif(10)
y <- runif(10)
plot(x,y,axes=F)
xat <- pretty(x)
yat <- pretty(y)
axis(1,at=xat,label=paste(100*xat,'%',sep=''))
axis(2,at=yat,label=paste(100*yat,'%',sep=''))
box()

I believe that depends on the graphics driver, but I've never played
with las.  If it works for other kinds of plots but not barplots, then
I'd submit it as a bug report.
