Dear all,
Our quite basic function mtext() does wrong adjustments in some parameter
configurations. This gets obvious when using multi line texts: There is no
way to properly adjust text perpendicular to axis 2, for example.

m <- matrix(1:9, 3)
colnames(m) <- c("several\nlines", "several\nlines", "several\nlines")
par(mfrow=c(2,2))
barplot(m, horiz=TRUE, axes=FALSE, axisnames=FALSE, main="las=0 adj=0.5 is
fine")
mtext(colnames(m), 2, at=seq(0.5+0.2, by=1+0.2, length=3), las=0, adj=0.5)
barplot(m, horiz=TRUE, axes=FALSE, axisnames=FALSE, main="las=0 adj=1 is
different")
mtext(colnames(m), 2, at=seq(0.5+0.2, by=1+0.2, length=3), las=0, adj=1)
barplot(m, horiz=TRUE, axes=FALSE, axisnames=FALSE, main="las=1 adj=0.5 is
NOT fine")
mtext(colnames(m), 2, at=seq(0.5+0.2, by=1+0.2, length=3), las=1, adj=0.5)
barplot(m, horiz=TRUE, axes=FALSE, axisnames=FALSE, main="at las=1, adj=1
works the wrong direction", sub="no way to get adj=c(1, 0.5) with las=1 (or
2)")
