Hi, how are you? I have 1000 total columns with 100 rows and I have shown 4 columns of 100 rows below. I want the zeros to be read in as numerical or integer values rather than a character. Right now I have a 100x0 character matrix rather than a 100x1000 double matrix. What do I need to do to read in a .csv spreadsheet with counting the zeros as a numerical or integer value? Thank-you.

Hi, let me correct my previous post ("zeros in double matrix rather than character matrix"). I have included entries from the .csv file that has 4 columns of 1000 columns and 101 rows. The first column with the "Time (day)" will not be removed, but the row headers are the numbers 1 to 1000 and they will remain in the matrix. In the previous post I mentioned that R makes the
