Thanks Martin, your memory is clearly better than mine to remember that
from 2005! I thought that might have been the case and had read -man
whatsnew- but hadn't gone back further (I also neglected to state that
I'm using Stata 10.1 born 11 Aug 2008)
I just checked a few others and it seems that the old names are still
valid (see continued examples below), presumably to provide a degree of
backwards compatability when running scripts under old versions?
. clear
. set obs 10
obs was 0, now 10
. gen a = _n
. gen b = sum(a)
. egen b2 = sum(a)
. egen b3 = total(a)
. egen c = rmean(b b2 b3)
. egen c2 = rowmean(b b2 b3)
. egen d = rlast(b b2 b3)
. egen d2 = rowlast(b b2 b3)
. egen e = rmin(b b2 b3)
. egen e2 = rowmin(b b2 b3)
. list

Should these synonyms be mentioned in -man egen- or will they quietly
fade away in subsequent releases? (I guess Stata Corp. are the only
people who might answer that).
