hi all, i have a file of the following format that i want to read into a matrix: 010101001110101 101010010111110 010010100100000 ... it has no headers or row names. I tried to use read.table(), but it doesn't allow me to specify nothing as the column separator (specifying sep='' means whitespace for that function). read.fwf doesn't seem appropriate either.

Would readLines() work?

Hi Brian, Take a look at ?scan> x <- scan(file.choose(), what = 'list')Read 3 items> x[1] "010101001110101" "101010010111110" "010010100100000"> as.matrix(x)[,1] [1,] "010101001110101" [2,] "101010010111110" [3,] "010010100100000" HTH, Jorge On Tue, Oct 18, 2011 at 3:09 PM, Brian Tsai <> wrote:> hi all, > > i have a file of the following format that i want to read into a matrix: > > 010101001110101 > 101010010111110 > 010010100100000 > ... > > it has no headers or row names. > > I tried to use read.table(), but it doesn't allow me to specify nothing as > the column separator (specifying sep='' means whitespace for that > function). read.fwf doesn't seem appropriate either. > > [[alternative HTML version deleted]] > > ______________________________________________ > 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. >[[alternative HTML version deleted]]
