I have to perform forward subset selection on College data for the ISLR package, modelling one variable against the others on a training set. Normally I should have a list of variables like
Subset selection object
Call: regsubsets.formula(Outstate ~ ., data = College, subset = train,
method = "forward", nvmax=19)
17 Variables (and intercept)
Forced in Forced out
PrivateYes FALSE FALSE
Apps FALSE FALSE
Accept FALSE FALSE
Enroll FALSE FALSE
Top10perc FALSE FALSE
Top25perc FALSE FALSE
1 subsets of each size up to 8
Selection Algorithm: forward
Coefficients Model1 Model2 ...
PrivateYes * -
Apps * -
Accept * -
Enroll * *
Top10perc - *
Top25perc - -
etc.
But only this appears:
Subset selection object
Call: regsubsets.formula(Outstate ~ ., data = College, subset = train,
method = "forward", nvmax=19)
17 Variables (and intercept)
Forced in Forced out
PrivateYes FALSE FALSE
Apps FALSE FALSE
Accept FALSE FALSE
Enroll FALSE FALSE
Top10perc FALSE FALSE
Top25perc FALSE FALSE
1 subsets of each size up to 8
Selection Algorithm: forward
so I have no idea which variables are selected. I used to not have this problem but after maybe an update of R it doesn't show the selection of the stars anymore.
