axis.srt Extend generic axis() function with rotation of labels (string rotation, srt). If labels on the x-axis are parallel, then they are center justified; otherwise they are right-justified.

Description

axis.srt Extend generic axis() function with rotation of labels (string rotation, srt). If labels on the x-axis are parallel, then they are center justified; otherwise they are right-justified.

Usage

axis.srt(side, at, labels, srt, offset = 0.05, cex = 1, ...)

Arguments

side:	an integer specifying which side of the plot the axis is placed as follows: 1=below, 2=left, 3=above and 4=right.
at:	the points at which tick-marks are to bve drawn.
labels:	a character vector of labels.
srt:	string rotation in degrees, where 0 is horizontal
offset:	distance to draw labels relative to axis, scaled to dimensions of plot region.
cex:	character expansion factor for axis labels
...:	other arguments passed to axis(), *e.g.*, 'line' or 'col'

Examples

par(mar=c(5,5,5,5), xpd=FALSE)
boxplot(split(iris$Sepal.Length, iris$Species), xaxt='n')
axis.srt(side=1, at=1:3, labels=levels(iris$Species), srt=30)
axis.srt(side=3, at=1:3, labels=levels(iris$Species), srt=-30)
# draw horizontally instead
boxplot(split(iris$Petal.Length, iris$Species), horizontal=TRUE, yaxt='n')
axis.srt(side=2, at=1:3, labels=levels(iris$Species), srt=-30)
axis.srt(side=4, at=1:3, labels=levels(iris$Species), srt=30)
