The column names of the data.frames given to rbind must all be
permutations of one another.   E.g.,
    > rbind(data.frame(A=1:3,B=11:13), data.frame(B=14:17, A=4:7))
      A  B
    1 1 11
    2 2 12
    3 3 13
    4 4 14
    5 5 15
    6 6 16
    7 7 17
but not
    > rbind(data.frame(A=1:3,B=11:13), data.frame(B=14:17, C=104:107))
    Error in match.names(clabs, names(xi)) : 
      names do not match previous names
