Hi,
 I am a beginner at R and I would like to get information from a matrix,
where the numbers are larger than or equal to 50m . This means that plants
need to be apart at least  50m.  I  need to get the selection as in a way
that I can identify which pair of species are 50m or more apart.

here a peace of my matrix:

   Nauc_calo_1 Nauc_calo_2 Nauc_calo_3  Nauc_calo_1 0 22 36  Nauc_calo_2 22
0 165.8  Nauc_calo_3 36 165.8 0

Thanks
