Dear R developers, (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

OK, my journey to make lab machines automagically install & update all desirable R packages is nearing an end! The only question I have now is this: How can I control where the system prints the *.Rout file that is created automatically when the R batch program runs. In "man R" I don't find any information about it. When the cron job runs "R_installAll.sh" (see

This is just to alert the list about a new technical report http://www.stat.umn.edu/geyer/gdor/ that shows how to determine, using exact infinite-precision rational arithmetic when 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,

I upgraded from Fedora Core 4 to Fedora Core 5 and I find a lot of previously installed packages won't run because shared libraries or other system things have changed "out from under" the installed R libraries. I do not know for sure if the R version now from Fedora-Extras (2.2.1) is exactly the same one I was using in FC4. I see problems in many packages. Example, Hmisc: unable

Yesterday I was biten by a feature, which I find too dangerous. I wanted to use a factor `Subject?? as index into a data frame, whose row names were the levels of this factor. So there a 2 different possible interpretations of this: Either Subject is coerced to numeric or to character. The intended interpretation was, of course, `as.character(Subject)'. R did `as.numeric(Subject)??. This will

Version: 2.5.1 array() is inconsistent when given non-integral dimensions: > zz <- array(0,dim=c(4,3.01)) > dim(zz) [1] 4 3 > zz <- array(0,dim=c(201,4.05)) Error in dim(data) <- dim : dim<- : dims [product 804] do not match the length of object [814] [IMHO the code that did this is broken. My copy of it has been fixed. Consistent behavior and/or a clearer error message

arrows() seems to hang when either x or y scale of the plot is logarithmic and the arrows requested go beyond the plot (by more than a certain amount). I didn't go into C code to find it, but here's a function that exercises the bug a bit ... arrow.bug2 <- function(y0=1,y1=10,log="y") { plot(c(0.1,1),c(1,10),log=log) arrows(x0=0.5, y0=y0, x1=0.5,

Try this: fn <- "tmp.dat" x <- 1:3 dump("x",file=fn) file.info(fn) ## 9 bytes file.copy(paste("./",fn,sep=""),fn,overwrite=TRUE) file.info(fn) ## 0 bytes (!!) Normally file.copy() checks and disallows overwriting a file with itself, but it only checks whether character string 'from' is the same as character string 'to'

Just starting a new thread so that it''s easy to follow. I just submitted a patch at trac to add a new class method called "set_default_values" ( not a great name I think ), which lets you do all kinds of crazy stuff with setting default values. This ticket is at http://dev.rubyonrails.org/ticket/9093 and example pastie is at http://pastie.caboo.se/81925 It also lets you make

I have found a quite strange (to me) behaviour in Sweave. It only occurs in the following situation: 1. define a variable in one chunk 2. use it within a subsequent figure-generating chunk 3. delete it at the end of that same chunk Then the Sweave driver chokes, not finding the variable name when generating the figure Example: % document bug2.Rnw \documentclass{article} \usepackage{Sweave}

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

Yes, Ive fixed 1 of the 2 problems at install. Im testing fix 2 atm, and ask @technical for extra info. There are 2 bugs with the upgrade of 4.8 to 4.9. For others, please note, i've only tested this on debian with the debian packages (experimental) and my own packages. Bug 1) at install samba is unable to start due to : a change (commit) 0b261dc4e3f2 in 4.9 that requires to have

Hello, Is this a bug in clang, or a bug in my thinking? /Joe Armstrong /* When I compile the following program I get different answers in clang and gcc. $ gcc bug2.c $ ./a.out j = 40 $ clang bug2.c $ ./a.out j = 41 I think the correct answer is 41. If my understanding of C is correct (which, or course, it might not be) the incremented value of i++ is first made available

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 <-

So... Are 40 and 41 the only legal behaviors or are there more?
