Subject: [R] barplot
Hi,
a couple of simple graphics questions:
1. I have a little function that makes bar plots. Now I would like to
limit the Y-axis outside this
function (that means after calling the barplot() command) depending on
the data to be plotted .
Does anyone know how to do this ???
Perhaps try the barplot() function that already exist in R?
It already allows you to set the axis limt (ylim and xlim).
2. When using barplot() and limiting the yAxis, R draws the bars below
the x-axis. How can I avoid this problem ??
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!
Cheers,
