Hello, I am using a number of large matrices in a project. I read a couple of the matrices using the read.csv command. However in some instances, R does not recognize the resulting matrices as consisting of numerical values (I suspect R considers them as strings or factors)
for instance when I try the following command (consider aMatrix is a matrix), > range(aMatrix[,1]) R returns > NA I get the same output when I try the max and min commands. Basically R does not recognise the matrix as consisting of numerals. However when I inspect the matrix the entries appear to contain numerical values. Is there something I am doing wrong? Is there anyway of coercing R into recognizing the matrix as consisting of numerals? -- View this message in context: http://www.nabble.com/Matrix-entries-not-recognised-as-numeric-tf4466621.html#a12735603 Sent from the R help mailing list archive at Nabble.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.
