[R-sig-Geo] Fwd: help with matrix

[Kátia Emidio]

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 50m.  I  need to get the selection(the results) as a
matrix or another object that allows me to identify which pair of species
are 50m apart. Attached it is an example...

Thanks
