Thank you, Sarah! Yes, unlist() looks like it will do just what I need. Thank you. I took a different tack. I'd changed the function returning A to coerce the row from the data.frame using as.numeric(). Any reason to prefer your way or mine? thanks again, Nick On Tue, May 1, 2012 at 2:08 PM, S

Thank you, Steve and Sarah, for your swift replies. I didn't know about dput(). class() returns "matrix" for A, B, and C, but here: > class(A) [1] "matrix" > class(B) [1] "matrix" > dput(A) structure(list(1239814462, 1239814601, 14349, 3, 4, 0, 12, 46601, 17801, 12401, 106001), .Dim = c(1L, 1

Hi Nick, We absolutely need a reproducible example, with code and data, to be able to help you. Because otherwise I can't replicate your problem: > A <- matrix(1:5, nrow=1, ncol=5) > B <- matrix(6:20, nrow=3, ncol=5) > C <- rbind(A, B) > A [,1] [,2] [,3] [,4] [,5] [1,]1234

[R] rbind-ing numeric matrices

2012-05-01 Thread Nick Switanek
Good morning, I'm running into trouble rbind-ing numeric matrices with differing numbers of rows. In particular, there seem to be issues whenever a one-row numeric matrix is involved. Assume A is a numeric matrix with 1 row and Y columns and B is a numeric matrix with X rows and Y columns. Let C
