Re: [R] setting attributes
David did help already, but if you want literally what the Introduction uses then you'll need a vector with as many elements as the final matrix (in David's example recyling applies to give 100 elements from the original 10). z - rep(0:9, each = 10) attr(z, dim) - c(10,10) That's simply a different route to the one shown by David, where the repetition of z values is made explicit.

Re: [R] setting attributes (SOLVED)
The learning curve of R is rather steep at start. Yes, it can be. I think the general advice would be to get a good Intro to R book if you're just starting out. That's certainly my advice. Or, get a book on some methods you're interested in that uses R (the Springer useR! series is really useful for this.) --Erik __ 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.
