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 Dr.ssa Erika Frigo Universit? degli Studi di Milano Facolt? di Medicina Veterinaria Dipartimento di Scienze e Tecnologie Veterinarie per la Sicurezza Alimentare (VSA) Via Grasselli, 7 20137 Milano Tel. 02/50318515 Fax 02/50318501 ----- Original Message ----- From: "jim holtman" <jholtman a gmail.com> To: "Erika Frigo" <erika.frigo a unimi.it> Cc: <r-help a r-project.org> Sent: Tuesday, March 04, 2008 6:13 PM Subject: Re: [R] problem
Is it just a file with a million values or is it some type of a structure with a million rows of indeterinent columns? If it is just a million numbers, you can easily read with is 'scan' or 'read.table' with no problem. I work with data structures that have several million rows and 4-5 columns without any problems. What is the format of the input? On 3/4/08, Erika Frigo <erika.frigo a unimi.it> wrote:
