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 -- Kátia Emídio da Silva DSc Eng. Florestal Manaus/AM Forestry Engineer Manaus/AM-Brazil [[alternative HTML version deleted]]
