[R] Logistic regression for large data

Dear R users, I have a database called Base.csv (attached to this email) which contains 13 columns and 8257 rows and whose the first 8 columns are dummy variables which take 1 or 0. The problem is when I wrote the following instructions to do a logistic regression , R runs for hours and hours w
