variable importance about flexsdm

[CWen001]

Hello.

Same question here. I'm wondering if it is possible to have functions to analyze variable importance in the future.

Thank you very much for your fantastic package and kind consideration. @sjevelazco

Definitively, this would be a great addon for the package.

Same, I want to use this package for an SDM but can't seem to find variable importance =/... Has anyone found this function yet?

Hello, You can use fitMaxnet::varImportance, and something like that: # Importância das Variáveis (fitMaxnet) maxent.varimp <- fitMaxnet::varImportance( theModel = with(maxent.tune.model, model), occSWD = as.data.frame(presence.points.model), bkgSWD = as.data.frame(background.points.model), responseType = "cloglog", numReplicates = 50 ) maxent.varimp <- data.frame(maxent.varimp) maxent.varimp$Var <- row.names(maxent.varimp) maxent.varimp <- arrange(maxent.varimp, Var) file.name <- paste0("Plot ", count.plot, " - Var Permutation Importance FINAL Model.tiff") file.name <- iconv(file.name, to = "ASCII//TRANSLIT") file.name <- file.path(sdm.folder, file.name) count.plot = count.plot + 1 tiff(filename = file.name, units = "cm", width = 20, height = 12, res = 400) maxent.varimp %>% arrange(maxent.varimp) %>% mutate(Var = factor(Var, levels = Var)) %>% ggplot(aes(x = Var, y = maxent.varimp)) + geom_col(fill = "#076FA2", width = 0.6) + geom_text(aes(label = paste0(maxent.varimp, "%")), hjust = -0.1, colour = "black", fontface = "bold") + coord_flip() + xlab("") + ylab("Permutation importance (%)") + scale_y_continuous(limits = c(0,85), n.breaks = 10) dev.off() Keep in mind that it's not the same as Maxnet jar implementation variable importance. Please refer to package documentation for details. I'm using flexsdm for almost all my modeling frameworks. It's very easy, powerful, and supports any programming framework you wish to use. Kind regards,

Hi all
We are working on new functions to calculate variable importance. We hope to publish them soon in flexsdm (maybe in December)
