[FORGED] Re: Example of the use of the "crt" graphical parameter?

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.

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.

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,

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.
