[R] Line breaks in documentation \useage

Hi again, R community. I wonder how you do line breaks in \useage{} section in .Rd files. I am sure there's some tutorial for this somewhere, but I just haven't found it. I have tried \\, \cr, \br and \newline, admittedly arbitrarily, but all of these produce warnings or errors. br, M

[R] Loss of dimensions in subsetting arrays

ly, you can get rid of this by writing as.matrix, as.array(...) but that generates extra lines of code. This is really annoying. Does anybody know how to turn this behaviour off? best, Markku Karhunen Uni. Helsinki __ R-help@r-project.org mai

[R] Regularized logistic regression

Hi Community, I would like to do regularized logistic regression, e.g. lasso, plasso or ridge regression. Can you recommend any packages? Low memory requirement / computational cheapness would be a plus. Markku Karhunen Uni. Helsinki __ R-help

Re: [R] ODE's in R

Thank you all. We must think about implementing these packages. In the meantime, I should clarify my question: Is there any evidence that doing the dumb for loop discretisation is any more dangerous in R, than in any other language? Apparently not? Best, Markku Karhunen > have you looked
