to trigger the bug:
plot(0:1,0:1)
text(0.5,0.5,"abc",srt=3D-1e-9)
this doesn't happen for positive, small srt,
or for negative srt with magnitude greater
than about 1e-8 (the example in plot.phylo
in the ape package triggers it, with a
srt value of -3e-15).
plot(0:1,0:1)
for (i in 1:10) {
cat(i,"\n")
text(0.5,0.5,"hello",srt=3D(-10^-i))
}
I have traced this a fair ways into
the C code -- I think it happens somewhere
in clipText -- but I'm not sure. Sorry not
to be able to provide a fix at the moment.
This is on Ubuntu 6.06, not sure whether
it affects other platforms or not ...
