Re: st: Producing a matrix of histograms

[Nick Winter <nw53@cornell.edu>]

I think

  . histogram bp , by(age ses, cols(5))

should do it for you... you may have to add the holes() suboption to the 
by() option, if there are unpopulated age-ses cells.  For example:

  . histogram headroom, by(foreign rep78, cols(5) holes(6 7) )

does this for the much-analyzed auto data.
