plot.envfit/move labels
...could not find an answer to his question. I have the same problem: While preparing figures of 'envfit' plots with vegan for publication, I ran into a layout problem, that I found no solution for in the literature or the help archive: The labels of the vectors that indicate correlations of environental variables sometimes overlap with each other or with other content of the figure. Hence, I would like to rearrange them. Is there a possibility to specify where the vector labels are plotted or, alternatively, is it possible to plot vectors only, so that the labels can be placed with 'text'...
