Hello,
I am trying to find the rank of an observation of a variable across a set of variables. My data looks something like this:

x1|x2|x3|x4
50|10|30|60
20|60|10|40

I want to generate a variable for the rank of x1 compared to the values of x1, x2, x3, and x4 for each observation in the data. I have tried using

-bysort x1 x2 x3 x4: egen rank1=rank(x1)-

but it is returning a variable of all ones, which is not correct. Using the data above, I'm look for variables that are:

rank1|rank2|rank3|rank4
2 |4 |3 |1
3 |1 |4 |2

Any help would be much appreciated.
