I have been generating some biplots to show the contribution of some variables to the cluster I see in the PCA plots, however, I can’t find a way to get rid of those variables with less weight. The image is so busy (hundreds of vectors) that it is not worth it to use it. Is there a way to set a cutoff to show those with more weight.
I have had a look at the ‘help’ tool to see if there is an argument that allows me to customise the code, but I have not found any.
Any help more than appreciated.
