R help - May 2017 - Example of the use of the "crt" graphical parameter?

Hi, folks.  This is an issue that we've defined away, but I recently
thought it would be useful to rotate characters in some marginal text
in a base-R plot.  I made a few stabs on using the "crt" parameter but
was unsuccessful.

I'm deliberately omitting details of my attempts, as I want just to
focus on the following: if you know of any working example of the use
of that parameter. will you please send me a link to it?  Thanks.

Hard to know what you want or did without code.

But, a guess: did you want the "srt" parameter and not 
"crt"?

Of course, it's always useful to read the man page, in this case for
?par, where it says:

(for crt):  "A numerical value specifying (in degrees) how **single
characters** should be rotated. It is unwise to expect values other
than multiples of 90 to work. Compare with srt which does string
rotation." [note: "string" = several characters = text]


Cheers,
Bert

Thanks, Bert.  I *did* mean crt, and I did read (and re-read) the man
page.  What I'm lacking, and the only thing I'm asking for, is a
working example of the use of that parameter.

FWIW:

"srt = 90" should rotate the whole string "aaaaaa" 90
degrees in a
call to text(), and it does.

I interpret "crt =90" to rotate the individual letters of
"aaaaaa" 90
degrees, but it does not on my graphic device, RStudioGD.  It probably
works on some other devices, but I don't know which ones.

HTH.

Cheers,
Bert

Hi Michael,
The arctext function (plotrix) does something similar, and the code
could be modified to do what you request. If you do want a working
function, it wouldn't be too hard to program.

Bendy like spaghetti :-)  Thanks, Jim.  I wasn't aware of plotrix, and
it does seem to be a cornucopia of useful, graphical stuff.

In this case, my quest for rotating characters stemmed from what you
might call a PHB request that I was eventually able to work around.  I
posed my original question here just out of curiosity (and
frustration, I guess).
