Hey,
Just started getting this error message using ENMeval and the maxent GUI (maxent.jar through Dismo):
In matrix(as.numeric(d)) : NAs introduced by coercion.
I am running univariate models with RM = 0, to examine how scale effects the predictive ability of models (selecting the optimal scale for a final multi-scale model). It runs fine for most of the variables I am using but then I get this error for other variables.
