Subject   st: how to generate row mode

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
