I am perfectly aware that this question is not an R question, at least
not yet, but I have not succeeded in finding what I want in other
ways, so ...
What I am looking for are two algorithms, preferabley in Pascal, but
other languages may do. For (a) systematic (complete) permutations
for grouped data with unequal group sizes, and (b) random permutations
for the same kind of data. I know of one source: E. S. Edgington
(1980): Randomization Tests (program 4.1 and program 4.3), but those
are written in Fortran with a lot of GO TO's which probably would not
be very efficient even if I managed to manually these programs and do
a correct translation. There must be some more modern ones around,
but where?
I need the algorithms for a program I have written for exploring
structural balance in sociometric group structures.
