Goodmorning Jim,
My file has not only more than a million values, but more than a million rows and moreless 30 columns (it is a productive dataset for cows), infact with read.table i'm not able to import it. It is an xls file.
How do you import your million rows and 4-5 columns files? thank you
regards
