[Bug]: varImp and maxentVarImp plots are not comparable

[rjaffe-ramboll]

Describe the bug

varImp returns a data.frame with two columns while maxentVarImp returns a data.frame with three columns.
plotVarImp is simply plotting the first two columns, which are different. Plots are thus not comparable.

Steps to reproduce the bug

library(SDMtune)
## Calculate variable importance
vi1 <- varImp(maxent_model, permut = 10, progress = TRUE)
vi2 <- maxentVarImp(maxent_model)

## Plot variable importance
plotVarImp(vi1) # Plots Variable and Permutation_importance
plotVarImp(vi2) # Plots Variable and Percent_contribution
