[R] Example of the use of the "crt" graphical parameter?
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. -- Mike On Mon, May 1, 2017 at 2:08 PM, Bert Gunter <bgunter.4567 at gmail.com> wrote:> 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.

Hi I do not recall ever using crt. A grep of the source code suggests that no user-level functions ever refer to it either. In other words, it appears to be basically unimplemented. Specifically with regard to text in the margins of a base plot, in addition to every function ignoring crt, only the text() function listens to srt (and that draws in the plot region, not the margins); mtext() (for margin text) only listens to las, so can only do horizontal or vertical.

Hmm. Thanks, Paul. That would explain the dearth of examples. -- Mike On Mon, May 1, 2017 at 4:42 PM, Paul Murrell <paul at stat.auckland.ac.nz> wrote:> Hi > > I do not recall ever using crt.
