Hi,
I have a question related to the function "boot.relimp" (package relaimpo).
I have a model with numerical predictors and one dummy (class) variable. I
would like to calculate the relative importance of the predictors but I have
some problems with the dummy variable.
The name of the linear model is "lmbroadst.lc" and the dummy variable is
"datacon.landcover_gb" (with 7 levels). I write the command as:
boot <- boot.relimp(lmbroadst.lc, b = 500, type = c("lmg", "last", "first"),
rank = TRUE, group = datacon.landcover_gb,
diff = TRUE, rela = TRUE)
The error message is:
Error in boot.relimp.lm(lmbroadst.lc, b = 500, type = c("lmg", "last", :
argument 5 matches multiple formal arguments
What is the correct syntax to include the dummy variable?
Thank you very much for your help!
Gabriela Bucini
