Re: st: Long to wide with monthly frequency

[Kyle Hood <kyle.hood@yale.edu>]

reshape long ---, i(id ) j(year) should give you id year 30.02. 31.03. 
etc.

then rename all your variables
foreach var of varlist *.*. {
local vn = substr( "`var'" , 1 , 5 ) ;
rename `var' "`vn'"
}

then reshape based on i(id year) j(month)

then rename again and reshape again.  (you can use renpfix before the last 
reshape so that your final variable has a name).
