st: how to generate row mode

["Fernando H. Andrade" <fandrade@umich.edu>]

Hello

I am trying to compute the equivalent to a rowmode, a function similar to 
rowmean in the egen command. i think the ado for a rowmode function (which 
may compute the mode across several variables) does not exist, does it? as 
an alternative i thought to reshape the data and collapse it using the mode 
but the mode is not a function to collapse the data.
is there a way to compute the mode across a set of variables for each 
subject?

to be more concrete:
this is the structure of the data

subject p1  p2  p3
1       2   2   4
2       1   1   3
3       2   2   4
4       1   1   1
5       3   4   4

i would like to generate a new variable containing the mode across p1 to p3 
for each one of the subjects such that for subject 1 the generated value 
would be 2, and 1, 2, 1,4  for subjects 2,3,4,5 respectively.

thank you very much for your time and attention

Fernando
