[R] Convex hulls after nMDS or PCoA

2020-05-11 Thread Fernando Archuby
Dear all. I need to build convex hulls around groups of points of an ordination (nMDS or PCoA). The groups were independently established with cluster analysis. I have learnt to plot convex hulls but would need to create every of the 21 groups independently. Do you know how could I just add the hul

Does increasing the value of k (the second argument) help? Also, if I understand the documentation correctly, the first argument should a single string, not a data.frame. I note that the paste function (with collapse="") can be used to turn a character vector into a single string. On Sat, May 9,

It is a nice dream, but it is really abdicating ethical responsibility to the computer instead of the researcher. And I personally don't trust computers over people for this. What could go wrong? First, how do you guarantee that the statistical plan was locked in place before the data was collec

Out of curiosity, and considering the bewildering array of projections and grids in use for various mapping purposes, you seem to be saying in your example 2 that the grid coordinates number south to north and east to west. Given scale of the coordinate numbers, would that be a national grid syste
