This code (within a do-file)
. sum year
. local minyear = r(min)
. local maxyear = r(max)
. local yrdiff = `maxyear� - `minyear� // T-1
Generates the following result (and error):
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
year | 2244 1979.5 12.70126 1958 2001
`maxyear� invalid name
r(198);
When I type the same code on the command line, I don't get the error --
however, when I erase and retype the code within the do-file, I get the
same error. I am running Stata/SE 9. I really have no idea what is going
on. I have scrutinized for spelling, etc. The code that I sent was
copied out of the do-file directly. I do wonder about the right single
quote (it looks funny), but I am using Stata's do-file editor, and am
using the single-quote-key directly to the left of the "enter" key. Can
anyone help?
