[R] Increasing the maximum number of rows

[Alex Ruiz E.]

Hi thank you both for your answers. 

I did verify that the number of rows in the csv is actually ~207,000,
both in the MySQL output and then directly in the csv file. The line
128328 looks exactly as all others above and below.

I tried the comment.char and quote parameters and it turns out that the
quote parameter worked. I appreciate the pointer.

Regards,
Alex
