I am looping over many data files and reading in the data with F <- read.table(filename) to read in a 22000 by 15 matrix. Works fine on the first matrix F, but I get the following error when the second file is read into F:
Error in "row.names<-.data.frame"(*tmp*, value = row.names) : duplicate row.names are not allowed I have tried picking a column of the matrix and making that my rownames by doing rownames <- as.vector(F[,4]) -but that does not work. Each row in my matrix is not unique. Any suggestions greatly appreciated.
