How about like this:
t1 - data.frame(row.names=c('c1','c2','c3','c4'), mk1=c(1,1,0,0),
mk2=c(0,0,0,1), mk3=c(1,1,1,1), mk4=c(0,0,0,0), mk5=c(0,0,0,1), S=c(4,5,3,2))
t1
mk1 mk2 mk3 mk4 mk5 S
c1 1 0 1 0 0 4
c2 1 0 1 0 0 5
c3 0 0 1 0 0 3
c4 0 1 1 0 1 2

Below is an example of what I'm trying to do.
Essentially I want to produce all unique 1 x 1 combinations of certain columns
from a dataframe, and join these
2 matches
