It was exactly what I needed, thank you.

Hi,
I'm building a graph (barplot) in which the X axis label
disappears.
I tried to use the option mgp of par() and I could not
get the desired result.
Note that want the axis labels horizontally.
caes = c(37,20,19,16,75,103)
names(caes) = c("Pinscher", "Pastor \n Alemão", "Poodle",
"Rottweiller", "SRD", "Outros")
caess = sort(caes, decreasing=F)
par(mar=c(3, 5.7, 1, 1), mgp=c(4.5, .5, 0), las=1)
You've set margin 1 too small. The barplot() function
puts the x axis label quite far from the plot, so you need
something like
par(mar=c(6.1, 5.7, 1, 1), mgp=c(4.5, .5, 0), las=1)
to give room for it. I think it would look better with
the label closer, which you can do using
mtext("Frequências", side=1, line=3)
(and this would work with a smaller margin, but not as
small as 3). For example,
caes = c(37,20,19,16,75,103)
names(caes) = c("Pinscher", "Pastor \n Alemão", "Poodle",
"Rottweiller", "SRD", "Outros")
caess = sort(caes, decreasing=F)
par(mar=c(4.5, 5.7, 1, 1), mgp=c(4.5, .5, 0), las=1)
barplot(caess, cex.axis=1, cex.names=1, ylab="Raças dos
Cães",
xlab="", bty='l', col="LightYellow",
horiz=T, xlim=c(0,120))
mtext("Frequências",side=1, line=3)
abline(v=0)
barplot(caess, cex.axis=1, cex.names=1, ylab="Raças dos
Cães",
xlab="Frequências", bty='l', col="LightYellow",
horiz=T, xlim=c(0,120))
abline(v=0)
Suggestions?
