Dear R Listserve,

I'd like to take my results from the envfit function in the vegan package,
such as those below, and make a vector plot in a graphing package like
Sigma Plot. When graphed in R, it is my understanding that the results
are scaled depending upon the plot axes.  Does R just multiply each
dimensional value (Dim1, Dim2) by a scaler to get X and Y coordinates for
each arrow endpoint?  If so, is there a way to view the scaler for each
given axis?  Any help on this would be greatly appreciated. Best, Steve
