That's a call to the replacement function split-(), which is defined as: get(split-.default) function (x, f, value) { ix - split(seq(along = x), f) n - length(value) j - 0 for (i in ix) { j - j%%n + 1 x[i] - value[[j]] } x } Andy From: ronggui i

Re: [R] error loading Matrix in Mac OSX 10.4

I think you need to ask on the R-sig-mac list with many more details. My understanding is that Matrix.so should import something like libintl_dgettext and that the R executable should export it. Hence my suspicion is that your build of R is the problem rather than the installation of Matrix.

Hi Veronika, StepAIC does not do any test. But you may do a likelihood ratio test on the difference between deviance of two models to judge which model to use, simply like this, 1 - pchisq(deviance.i - deviance.j, df.i - df.j) And then check whether the returned p value is small enough...
