Inn addition to my earlier post, note that it is not a good idea to name
the -graph- according to the string variable you are conditioning on.
Comment in the fourth string in this example to see that this causes
problems:
**************
clear*
input str10 mystr
"here"
"there"
"everywhere"
//"Allentown-Easton"
end
compress
expand 10
gen x =_n
gen y=rnormal()
levelsof mystr, local(str)
foreach lev of local str{
tw (line y x if mystr=="`lev'"), /*
*/ name("`lev'", replace)
}
**************

Subject: st: Looping over values of a string variable to create twoways
Hi everyone: I would like to write a foreach loop that will produce a
separate twoway graph for each value of my string variable msa_name.
When I enter:
levels msa_name, local(MSA)
foreach i of local MSA {
#delimit;
twoway (line yvar1 xvar if msa_name==`i' & state1==1, lpattern(dash))
(line yvar2 xvar if msa_name==`i' & state1==1, color(navy) yaxis(2)),
title("`i'",color(black) placement(west) justification(left))
legend(off)
saving(`i', replace);
};
Stata tells me, "end of do file," but does nothing.
In an attempt to isolate the problem, I tried the simpler:
foreach i of local MSA {
twoway line yvar1 xvar if msa_name==`i' & state1==1 & county1==1,
lpattern(dash)
}
which returns, "Allentown not found." The first value of msa_name is
"Allentown-Easton."
I seached the archives and did find a similar query, but I still could
not solve my problem.
Thanks,
Dorothy
