I have 40 columns in my dataset. When I do the model as below, I get this error but when I reduced the features to 12, it works. I want to use brute for process to select the best model for my work.
p <- glmulti(Severity~., data= model_scaled_center,crit=aic, level=1,method="g", family=gaussian,fitfunction=glm,confsetsize=10)
Error in .subset2(x, i, exact = exact) :
attempt to select less than one element in get1index
