[R] Example of the use of the "crt" graphical parameter?

[Bert Gunter]

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
