My guess is that you need to do more renaming.
The key principle here is that -reshape- thinks
of variable names to be -reshape-d as
stub + suffix
So, I think you need to -rename- (e.g.)
Opinion?C
as
OpinionC?
-renvars- is one way to do it which
some people like, and some don't.
It's more instructive
to do it from first principles.
That could be
foreach v of var Opinion?? {
local letter = substr("`v'",-1,1)
local digit = substr("`v'",-2,1)
rename `v' Opinion`letter'`digit'
}
With that it seems that the key variables
would all have suffixes 1-3.
