Richard, thanks for the reply. Actually, I have tried giving the -rspread-
command again several times after reading your reply and the results are
puzzling. I had the following for the first three attempts:
1st attempt: there was what looked like a correct output, but with the error
message:
invalid 'Files'
r(198);
2nd attempt: worked fine
3rd attempt:
mdmean already defined
r(110);
I'm using windows xp. By the way, from what you said about the rewriting,
does it mean the new version would appear in the SJ before it can be used?
Thank you.
Louis

I am the original author of rspread
I was out of the office all day yesterday, so I only seeing the messages
today.
I tried -rspead- on the auto data and had no problems (Stata 9 in Windows
XP) so am not sure what is going on. However, it is also the case the Nick
Cox very generously took on the re-writing, and bringing up to date, of the
program and this should appear in a forthcoming SJ -- much thanks to Nick
The answer to question 2 is "no" -- the program was never meant to overlay
Lorenz curves directly

Dear All,
I have two questions:
1. I've been trying to explore how -rspread- works. I gave a command and
had an output, but with the error message - invalid 'files' (198) - below
the output. The command was:
rspread welfare
The output looked alright, but I don't understand why the error message
was also generated. I've checked to be sure there are no zeros or missing
observations, using - count if mi(welfare) - and
- count if welfare==0 -. Each of the last two commands gave an ouput of 0.
Can anyone explain what the problem is?
2. Can -rspread- be used to generate two or more Lorenz curves within the
same axes?
Thank you.
Regards,
Louis
