Anyone had any thoughts on the item below? If the problem is with my config, I'd like to be guided towards how I might resolve it. If it is a bug in rc7, it would be good to fix it, and I'd be happy to beta-test. -- : David Lee I.T. Service : : Senior Systems Programmer Computer Centre : :

Hello, I am struggling to figure out how to analyse a dataset I have inherited (please note this was conducted some time ago, so the data is as it is, and I know it isn't perfect!). A brief description of the experiment follows: Pots of grass were grown in 1l pots of standad potting medium for 1 month with a regular light and watering regime. At this point they were randomly given 1l of one

Could someone confirm, please, that this bug report and its proposed fix are being checked? 1. Is my analysis (message below) about right? 2. Is my proposed patch (attached) about right? 3. Is this being addressed for "rc8" (or whatever) and its successors? Many thanks. -- : David Lee I.T. Service : : Senior Systems Programmer

I have a plot where the values of the y axis go from a positive number to a negative number and I want the x axis to intercept at zero rather than at the bottom of the y axis, regardless of its value. Can anyone help me to do this? Thanks in advance Vivien Vivien Kent MSc Oxon PhD candidate Evolutionary Anthropology Research Group Department of Anthropology Durham University Dawson

Timo - it would be very convenient if we could get a variable that held the real client ip for use in logging with director/proxy setups. It's clearly already passed around in client->user->remote_ip but at this point, I don't see anyway to get it into the logs and it would take me ages to figure out the Right place to add it since client->user doesn't seem to be available in

Dear all I need to obtain an estimate of the 50% lethal dose (LD50) from a logistic regression model obtained by applying the glm procedure to some binomial data. The model appears to fit the data very well. I used dope.p from MASS to try and find LD50. The following output appears: > dose.p(iso.glm.logit, cf = c(1,3), p = 1:3/4) Error in dose.p(iso.glm.logit, cf = c(1, 3), p = 1:3/4) :

I have just noticed that the last several versions of R that I have compiled all have the problem that functions which use regular expressions (gsub, sub and anything which depends on them) do not work. In particular, methods(print) either gives an error message or causes a segmentation fault. The problem is actually in gsub/sub which either return character(0) or cause a segmentation fault.

This is a minor question, but is there any difference between the two objects fred <- structure(1:10, dim = c(2,5)) and fred <- structure(1:10, .Dim = c(2,5)) Should I be using one rather than the other?

Am I right in thinking that there a discrepancy between the ?library documentation and the library() function? If I have a library called "patches", then according to the documentation (0.62.4) patches/R should contain source files like fred.R and george.R, but in practice the library only loads if both fred.R and george.R are given in a file called patches in the R subdirectory of

Is anyone else concerned with the way in which the R function parser relocates comments that occur after condional expressions in functions to before, i.e. fred <- function(x) { # wonder what x is like if (x>0) stop("Sorry non-positive x only") # that showed x big-time! x } but then fred is parsed and stored as "fred" <- function (x) { # wonder what x is

I am not sure that this is a bug, but it was unexpected -- of course my expectations are fallible, eg column ordering in model.matrix()! When an array is subscripted the names of the dimnames list are lost (v 64.1). fred <- array(1:12, 2:4, list(A = letters[1:2], B = letters[3:5], C = letters[6:9])) dimnames(fred) dimnames(fred[1, , ]) dimnames(fred[1, , , drop=FALSE]) In the first

I can generate a segmentation fault as follows, where I would expect a syntax error: fred <- as.list(1:10) lapply(fred, "[[") platform sparc-sun-solaris2.5.1 arch sparc os solaris2.5.1 system sparc, solaris2.5.1 status status.rev 0 major 0 minor 64.1

Can I suggest that in cov and cor the lines if (is.data.frame(x)) x <- as.matrix(x) if (is.data.frame(y)) y <- as.matrix(y) be replaced by if (is.data.frame(x)) x <- data.matrix(x) # coerce logical and factors if (is.data.frame(y)) y <- data.matrix(y) # likewise This would allow things like > data(iris) > cor(iris) which

Hi everyone, I do a lot of work with large variance matrices, and I like to use "crossprod" for speed and to keep everything symmetric, i.e. I often compute "crossprod(Q %*% t(A))" for "A %*% Sigma %*% t(A)", where "Sigma" decomposes as "t(Q) %*% Q". I notice in the code that "crossprod", current definition > crossprod function (x,

The following gives an immediate segmentation fault, v 0.90.1 "fred" <- function(x) { print(x); Recall(x-1)} fred(0) # segmentation fault at recursion 831 Obviously this recursion is non-terminating, but shouldn't it be caught and reported at some limit? In 0.64.1 we had Error: protect(): stack overflow at recursion 831. Cheers, Jonathan. Jonathan Rougier

According to the assign helpfile (0.90.1) the "assign" function is function (x, value, pos = -1, envir = sys.frame(sys.parent()), inherits = FALSE, immediate = TRUE) which is not quite the implementation, which is function (x, value, pos = -1, envir = pos.to.env(pos), inherits = FALSE, immediate = TRUE) This seems to have the following interesting effect.
