Hi, I am a new R user and am trying to construct a palaeoenvironmental transfer function (weighted averaging method) using the package rioja. I've managed to insert the two matrices (the species abundance and the environmental data) and have assigned them to the y and x values respectively. When I try and enter the 'WA' function though, I get an 'Error in FUN' message (see below for full values). Alas, I do not know what this means and have struggled to find similar problems to this online. Is there a step I've missed out between assigning the matrices and the WA function?
