Hi, What's the status of LLVM on Visual Studio? In particular, our application would like to generate some LLVM code, then call into it. Is this possible with the JIT compiler? Is it possible by creating & loading a .dll? Thanks, Martin

Hi all, update.default, which is the method used to update "lm" objects (among others), extracts the "call" element from it's first argument, updates it, then evaluates it in the parent.frame(). Shouldn't it be evaluated in environment(formula(object)), if that's non-NULL? I ask because I call "lm" from within a function, and the data argument is a

Martin Version: 2.7.1 OS: Ubuntu Submission from: (NULL) (75.150.115.86) The function write.arff, in the foreign library: - Can produce relation names with invalid characters - Doesn't use colnames() for attribute names when writing a matrix. Here's a better version: write.arff <- function (x, file, eol = "\n") { if (file == "")

Hi all, I'm trying to get a simple, linear decision surface from e1071's svm. I've run it like this: svm(as.factor(slow) ~ SLICE.3 + PSGR.7 + SOLUTIONS.6 + DR.10, y, kernel='linear', cost=1e6, class.weights=c('FALSE'=1, 'TRUE'=10)) According to the docs, kernel='linear' has a kernel u'v. Since I have 4 independent variables, I'd expect to

Hi, In the Linux (FC3) version of R, ctrl-\ quits R. This wouldn't be so bad, but on my keyboard, it's right next to ctrl-p and I tend to hit it by accident. Is there any way to turn that off? Best, Martin

Hi, First of all, thanks for the great work on R in general, and MASS in particular. It's been a life saver for me many times. However, I think I've discovered a bug. It seems that, when I use weights during an initial least-squares regression fit, and later try to add terms using stepAIC(), it uses the weights when looking to remove terms, but not when looking to add them:
