What is the best way to load a matrix from a text file if it's already in a matrix form? I'd like the parser function to automagically recognize that line separators indicate a new row. The technique I've been using is the following: output <- matrix(scan(inputFile), byrow=T, ncol=2) However, I don't want to have to specify ncol=2. Thanks! John
What's wrong with read.table? It's the principal function for reading data into R. -Andy
You could try: as.matrix( read.table( filename ) ) Date: Mon, 05 Jan 2004 14:54:30 -0500 From: John Hayes <jahaye at wm.edu> To: <r-help at stat.math.ethz.ch> Subject: [R] loading matrix from file What is the best way to load a matrix from a text file if it's already in a matrix form?
