I´m trying to create a correlation (with p values) between two different matrices (operational taxonomic units versus environmental paramenters) in R. I want to look at the specific correlations between individual OTUs and biotic parameters (not vectors versus community ordination).

The first table is this

biotic1 biotic2 T1 1.540184 3.080025 T2 1.354927 5.012977 T3 1.449712 4.715981 T4 1.146659 2.442083 X1 1.705184 3.881878 X2 1.182721 3.014836 X3 1.536956 2.636719 X4 1.808025 4.434525 A1 1.132737 2.135737 A2 1.506048 3.114281 A3 1.285308 4.363828 A4 3.008994 7.290423

and the second table

OTU1 OTU2 OTU3 OTU4 OTU5 OTU6 OTU7 OTU8 T1 109 80 175 14 71 46 61 39 T2 102 48 26 8 23 5 35 10 T3 26 19 61 3 68 13 10 29 T4 143 56 9 11 16 13 49 24 X1 70 36 20 15 39 9 26 12 X2 39 33 12 32 15 2 11 3 X3 43 17 2 14 8 2 7 2 X4 160 60 8 26 25 7 9 15 A1 90 73 41 15 22 23 33 7 A2 344 109 18 28 22 13 93 16 A3 65 16 15 9 5 10 18 6 A4 141 140 6 86 18 3 43 4

I have already tried cor() and corr.test() but it only seens to correlate values from the first table.

Any suggestion?

Thank you very much
