why don't you use a 'list' as the return value. The 'cbind' is going to
assume that each of the 'return[[..]]' have the same length or you are going
to get error messages:
> cbind(1:3,4:10)
[,1] [,2]
[1,] 1 4
[2,] 2 5
[3,] 3 6
[4,] 1 7
[5,] 2 8
[6,] 3 9
[7,] 1 10
Warning message:
number of rows of result
is not a multiple of vector length (arg 1) in: cbind(1, 1:3, 4:10)

I would assume a matrix like above is not what you want. So why don't you
just say:
return(split(return, list(regimef, assetf)))
