Hi Mr Plate, I have a little question
How to convert a rowname vector of numbers into a real column of the matrix, My problem is that I applied a rowsum function on a matrix. Then I get a matrix in which the names of the columns are the values of the group (numbers) Now I need to make calculation on the groups row. How to convert this vector of (rownames) into a real column in the matrix ? thanks by advance Jessica Gervais _________________________________________________________________ www.windowslivemessenger.fr ______________________________________________ R-help@stat.math.ethz.ch 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.
