st: RE: constructing the rank across variables

[Nick Cox <n.j.cox@durham.ac.uk>]

-egen- is in principle wrong here as it produces a single result variable. I suppose that does not rule out repeated calls to -egen-, but I think it is better in principle to think of a dedicated command that does this all at once. 

Already twice today I have referred to a review of this territory 

SJ-9-1  pr0046  . . . . . . . . . . . . . . . . . . .  Speaking Stata: Rowwise
        (help rowsort, rowranks if installed) . . . . . . . . . . .  N. J. Cox
        Q1/09   SJ 9(1):137--157
        shows how to exploit functions, egen functions, and Mata
        for working rowwise; rowsort and rowranks are introduced

Sorry for the repetition, but Jon perhaps did not pay attention to those threads, life being short and people being busy, and so forth. 

In any case, the brief abstract of the abstract above shows that a -rowranks- command already exists.

Could anyone recommend a way to create a series of variables that indicate the 
rank of a list of variables in a wide-format data set, akin to using the 'egen 
rank' function in a long-format data set? That is, how would one code up 'egen 
rowrank'?
