MuMIn package is installed but when I try to run dredge dunction, it says "Error in dredge(models) : could not find function "dredge". How to solve this problem?
I have glm models with species richness as dependent variable and other environmental factors like land use and disutrbances as independent variables. My codes for this specific section are: install.packages("MuMIn") library(MuMIn) models <- list(pmla1, pmla2, pmla3, pmla4, pmla5, pmla6, pmla7, pmla8, pmla9) model.selection <- dredge(models)
