Hi,
simple code:
<hansl>
set verbose off
nulldata 128
set seed 123456
foo = randgen(N, 10, 2)
freq foo --nbins=3
freq foo --nbins=4
</hansl>
Why I get 5 bins instead of 4 in the second freq call?
Regards,
Marcin

This is because the number of bins is forced to be odd, so 4 becomes 5. I
can't say right now why this happens, this is a very old area of the
source.
Whatever the reason, it is undocumented, so either we add a line to the
doc for the "freq" command or we remove lines 1675-1677 from
lib/src/describe.c.

Assiuming we give a user chance to decide how many bins he/she
wants I
prefere remove theses three lines from the source.

I've found another freq issue:
<hansl>
bundle B
matrix B.foo = mnormal(100,1)
freq --matrix=B.foo --plot=display
</hansl>
Is this a bug or expected behavior?
Regards,
Marcin

I'd say it's expected behavior. "B.foo" counts as an expression that
evaluates to a matrix rather than "a named matrix" as required.
However, the option parser could probably be extended to cover this
case.

So should this become an official feature request?
