[R] lattice panel fine control

[Bert Gunter]

You did not read the help files carefully enough.

The Help for panel.text tells you that it is the same function as
ltext. ltext lists a bunch of parameters, srt among them, and refers
you to the corresponding base R graphics function, which is text().

?text then refers you to par for this and other miscellaneous parameters.

?par then tells you that srt gives the string rotation in degrees, the
answer to your question.

So, yes, it's a bit rough going; but careful attention to the docs
DOES get you there.

"Men by nature long to get on to the ultimate truths, and will often
be impatient with elementary studies or fight shy of them. If it were
possible to reach the ultimate truths without the elementary studies
usually prefixed to them, these would not be preparatory studies but
superfluous diversions."

-- Maimonides (1135-1204)
