Hello,
I was wondering if there exists an (undocumented) option to save freq. histograms to the
disk as, say .png file. I can use the" --show-plot" option in a loop and then
manually save the figures thus created (even save them as icon and manipulate them). But
is there a way to save them to a file like it is possible with scatters and boxplots? I.e.
something like an "output=" option and perhaps even a way to pass additional
arguments via { set ... ; } ?
Many thanks as always

A very good question. I see no good reason why it shouldn't get the same
--output option as 'gnuplot' or 'boxplot'.
While we're at it, I notice that 'rmplot' does not have such an option,
either.
And in the doc for 'scatters' the line "--output=filename (send output
to specified file)" is included twice.
Finally, it might be useful to make the "binning" of the histogram
behind 'freq' available in a numerical matrix form, either by
introducing an associated 'freq' function, or by adding a $-accessor
that could be used after doing 'freq ... --silent'.
thanks,

Good points. I realize that I did something about some of this a
while back but apparently stopped short of completing or documenting
it. I've now updated the help text and brought "freq" into line with
similar commands. Here's the deal:
* Commands such as "gnuplot", "plot", "scatters",
"boxplot" and
"qqplot", which just produce plots, should all respect the
"--output=" option, taking an argument of either "display" or the
name of a file (which then governs the type of file produced).
* Other commands that can produce a plot but also produce textual
output ("rmplot", "leverage", "freq", etc.) all have a
option,
"--plot=", which also accepts a "display" or filename argument, but
in addition accepts "none" (which suppresses the plot that is
produced by default in interactive use).
Adding this "--plot=" option to "freq" means that two existing
options become redundant, namely --quiet (use --plot=none now) and
--show-plot (use --plot=display). I haven't yet removed these
options but I've dropped them from the help text and I'll mark them
as deprecated.
What I've described is now in git and snapshots.

Hello,
what a service! Thanks very, very much. I just tried the new commands and all works well,
except that one cannot use --plot and --silent (to supress the statistics printed)
together or use literals as with gnuplot, e.g.: { set title ""; } If that was
possible, too, it would be even more fantastic and allow to generate publication-ready
histograms ;) But even now with the new options present, one can produce .gp files
directly and easily fix things there via copy and paste. So this is not too important.
(The ' "icon label" <- ' option does not seem to work despite a
confirmative text is produced in the output window - the latter even if the --plot option
is active, too.).
But I feel a bit unthankful to ask for more. Please don't see it that way.

Not at all -- thanks for testing the new stuff!
I've now fixed a couple of the things you mention:
(1) --plot and --silent can now be used together (but not --plot plus
--quiet, the old option whose sole job was to suppress the plot).
(2) The mechanism for saving a "freq" plot as a named object in the
icon view should now work.
As for the gnuplot "literal" mechanism, I can see this would be
useful, but it would be more complicated to add that for all commands
that produce plots. I'll have to think about it some more.

Hello again,
I tested the new silent and icon save options for "freq". There are some
issues:
1) Saving to icons does not work in a loop at all
2) The --silent option does not work correct in a loop -- only the first iteration of the
innermost loop will work.
In both cases, no error message is printed. Nevertheless, it is not too much of a pain to
use it as it is now. It is great one can produce frequency plots automated! Saving to .gp
and hand-adding some literals then (including a line to produce a .png, etc.) is not that
much work either. Many thanks!

Thanks again for testing. I see what the problem is with --silent and
I think things should now be OK in git and snapshots.
