Both spaces and tabs are whitespace so this should be good enough (unless you can have empty fields): read.table(myfile.dat, header = TRUE) See the sep= argument in ?read.table . Although I don't think you really need this, here are some regular expressions for processing a header into the form

[R] SparseM and Stepwise Problem

2007-01-30 Thread davidkat
I'm trying to use stepAIC on sparse matrices, and I need some help. The documentation for slm.fit suggests: slm.fit and slm.wfit call slm.fit.csr to do Cholesky decomposition and then backsolve to obtain the least squares estimated coefficients. These functions can be called directly if the

Greetings R-helpers, I am attempting to fit an lme() while specifying a correlation structure, but I'm getting into trouble long before I get to that point. I am receiving the error: Error in y[revOrder] - Fitted : non-conformable arrays It doesn't seem to matter how simple or complex the model

One simple possibility -- if you can generate the X matrix in dense form is the coercion X - as.matrix.csr(X) Unfortunately, there is no current way to go from a formula to a sparse X matrix without passing through a dense version of X first. Otherwise you need to use new() to
