Re: st: alternate data management strategies for importing Excel matrices

[Sergiy Radyakin <serjradyakin@gmail.com>]

Dear Steve,

1) see if the -stack- command is useful in your case (standard Stata
command). As in e.g.:
do http://radyakin.org/statalist/2013121601/stackvars.do

2) I've noticed in your post 'kidney' is in different quotation marks
then the other words. Be careful, as it can be difficult to find
errors like the following:
do http://radyakin.org/statalist/2013121601/diff_q.do

Best, Sergiy.

I wish to convert these matrices into a single var of unique IDs as I will need to -merge- them with patient data shortly. My initial attempts were to use -reshape- but I couldn’t get past the r(498) error "variable _j contains all missing values”.
