[ONKELINX, Thierry]

Dear Eliza,

You question is not very clear. I think you are looking for the which() function.

Best regards,

Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey

Onderwerp: [R] combining column having same values


Dear useRs,
I have a matrix in the following form

 [,1]   [,2]   [,3]   [,4]   [,5]   [,6]   [,7]   [,8]   [,9]  [,10]  [,11]      1      1       3      2       3       1      1       2      3       3      2

and following is my desired output  (combining the column headers, having same values).
a<-1,2,6,7

b<-3,5,9,10

c<-4,8,11
Thanks in advance
Elisa
