This is a bug/misfeature report for R CMD check. The function tools:::.check_packages_used_in_tests Gives an apparently unintended error when checking the tests in the contributed package rcdd_1.1-3.tar.gz as found on CRAN. See the script below for details. The actual error reported is totally mysterious. * checking for unstated dependencies in tests ... NOTE Error in as.character(function (description = "", open = "", blocking = TRUE, : cannot coerce type '...

...lopers, (Apologies about previous incomplete e-mail, I fat-fingered a keyboard shortcut)?? I recently upgraded to 3.2.3 and am getting mystifying errors with my in-development code (available at https://github.com/gertvv/gemtc/tree/feature/regression). Every few hundred LPs that I solve using the rcdd package will result in a SEGFAULT in the garbage collector (address 0x10, cause 'memory not mapped') or an error about a list not existing. Downgrading to 3.2.2 works, but *only* after completely removing my local R packages and re-installing them. A subsequent upgrade to 3.2.3 will again b...

Dear Friends, Here is an algorithm for finding concave hulls: http://get.dsi.uminho.pt/local/ Has anyone implemented such an algorithm in R? RSiteSearch('concave hull') didn't reveal one (I think). _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology Postal Address: P.O.Box 400400, Charlottesville, VA 22904-4400 Express Parcels

Hi (If you're wondering, this is a Project Euler question :)) If I wanted to calculate the sum of the digits in the decimal representation of 2^1000, what would be a good way to go about that? I've tried the following methods: # Calculate the sum of digits in the decimal representation of 2^n # Only works for smaller values of n bsum <- function(n) { s <- 0 e <-

...n the MLE exists in a GLM (or for that matter in any exponential family, such as aster models -- contributed package aster) and what to do when it does not. This suggests many changes to glm, glm.fit, predict.glm, and anova.glm. Before any such changes could be implemented, the contributed package rcdd would need to be made recommended, which in turn would require that it be made available on Macintosh (the problem is getting the GNU bignum package GMP to compile with gcc, shouldn't be hard, but apparently is on Macs, but Jan de Leeuw has done it, so it's not impossible). The tech report...

Full_Name: S?ren Faurby Version: 2.4.1 and 2.7.2 OS: Submission from: (NULL) (192.38.46.92) There appear to be a bug in the estimation of significance in the binomial model in GLM. This bug apparently appears when the correlation between two variables is to strong. Such as this dummy example c(0,0,0,0,0,1,1,1,1,1)->a a->b m1<-glm(a~b, binomial) summary(m1) It is sufficient that all
