Perhaps try the barplot() function that already exist in R?
It already allows you to set the axis limt (ylim and xlim).

Again, it shouldn't happen. The codes below are directly extracted from the
barplot() documentation:
data(VADeaths, package = "base")
hh <- t(VADeaths)[, 5:1]
mybarcol <- "gray20"
mp <- barplot(hh, beside = TRUE,
col = c("lightblue", "mistyrose",
"lightcyan", "lavender"),
legend = colnames(VADeaths), ylim= c(0,100),
main = "Death Rates in Virginia", font.main = 4,
sub = "Faked upper 2*sigma error bars", col.sub =
mybarcol,
cex.names = 1.5)
It works. Try changing the "ylim = c(0, 100)" to other limits, it
still
works!
