Assuming you have created a data.frame from the text file you sent that is called RP:

My data.frame is not integer value . I want to convert the values to the nearest integer values for my matrix. Can you tell me how to do it in r. I am sending you the matrix where you can see a lot of decimal point numbers and all of them needs to be converted to integer values ---------------------------------------------------------- Vivek Das PhD Student in Computational Biology Giuseppe Testa's Lab European School of Molecular Medicine IFOM-IEO Campus Via Adamello, 16 Milan, Italy emails: vivek....@ieo.eu vchris...@yahoo.co.in vd4mm...@gmail.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
