Dear all, I have already looked at similar questions about this topic but I still have few doubts. when I run: data(varespec, varechem) library(MASS) ord <- metaMDS(varespec) (fit <- envfit(ord, varechem, perm = 999))
I get this output: ***VECTORS NMDS1 NMDS2 r2 Pr(>r) N -0.05738 -0.99835 0.2536 0.041 * P 0.61980 0.78476 0.1938 0.105 K 0.76650 0.64225 0.1810 0.098 . Ca 0.68524 0.72832 0.4119 0.001 *** are the numbers under NMDS1-2 the direction of the arrow or they show to which axis is the variable correlated? if I look at N can I conclude that N is negatively correlated to NMDS2, while K is positively correlated to NMDS1? is it possible to get the correlation coefficient of a variable with the axes? here we have r2 but I don’t understand if it refers to both of the axis or just one. thanks a lot for any help!
