[R] Why I get this error? Error in close.connection(f) : invalid connection

I don't understand why I can not close 'f'. This may be very simple, but I don't see why. Could somebody let me know? $ cat gzfile.csv ,V1,V2,V3,V4,V5 1,1,5,9,13,17 2,2,6,10,14,18 3,3,7,11,15,19 4,4,8,12,16,20 $ Rscript gzfile.R f = file(gzfile.csv) A = read.csv(f) A X V1 V2 V3 V4 V5 1 1 1
