Re: st: merging floats to make dates

[Nick Cox <njcoxstata@gmail.com>]

Your claim is quite incorrect. There is detailed documentation on
handling dates and your problem is included. The main help on dates
and times points you to the function -ym()- which can be used to
combine year and month values. For example,

. di %tm  ym(2012,1)
 2012m1

In your case you appear to need

. gen monthlydate = ym(var1, var2)

I don't understand what you mean by needing to use lags for this
problem. But note that in Stata "merging" overwhelmingly tends to mean
using -merge- to combine entire datasets.
