Hi:
I am using a subset of the below dataset to predict PRED_SUIT for
the whole dataset but I am having trouble with 'newdata'. The model
was created with 153 records and want to predict for 208 records.

# This works, it predicts for the whole dataset if done manually using the coefficients of m1
wolf$predicted<- -1.6166 + (-0.5777*wolf$RD_DENSITY)+((2.1672)*wolf$Forest)+((0.2279)*wolf$Shrub)+((-13.9071)*wolf$Ag)
dim(wolf)
wolf$prob99<-(exp(wolf$predicted))/(1+exp(wolf$predicted))
head(wolf);dim(wolf)
# How can I use predict here, 'newdata' crashes
predict(m1,newdata=wolf$predicted);wolf # it doesn't work
Thanks for any hints
