but you could have one: a <- data.frame(matrix(rnorm(100),10) # get some data class(a) # check for its class as.numeric(a) # whoops, won't work class(as.matrix(a)) # change class, and as.numeric(as.matrix(a)) # bingo, it works PF -- +----------------------------------------------------------------------- | Patrizio Frederic, | http://www.economia.unimore.it/frederic_patrizio/ +----------------------------------------------------------------------- ______________________________________________ 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.
