Using PCNM() in Vegan and calculating Moran's I
2 messages · Chase, Jennifer, Pascal Oettli
Hello, I generally use 'moran.test' and 'moran.mc' from the 'spdep' package. Regards, Pascal Le 19/12/2012 09:02, Chase, Jennifer a ?crit :
Hello- I am using the vegan package PCMN() because I need to use option of row weights (I am using CCA following the selection of the significant/positive PCNM variables). In the library PCNM (PCNM function), the Moran's I is calculated for you as part of the function. I see that I need to calculate Moran's I separately in order to retain the eigenfunctions with positive spatial correlation but could use help in doing so...I have looked up Moran's I in a couple different packages but am not sure what to use... Thanks! [[alternative HTML version deleted]]
