variance components
Dear All, I need to calculate the variance components in a mixed effect model (one fixed and one random effect) with REML (maximizing the proportion of the likelihood that does not depend on the fixed effects). In S+ there is the varcomp function, but I would like to do it in R. Is there a way to do that? Thanks! Katalin ___ Katalin Csillery Division of Biological Sciences University of

groups of boxplots
Hi, does anyone know how to make pairs of boxplots? E.g. 5 pairs of boxes. I figured a not very elegant way, by inserting a dummy NA field to the list where the data is given. So, where I have the dummy I got more distance between boxes, as a result it looks like groups. But I am having problems with putting the names under the groups, and the thick marks. Any better idea? Thanks, Kati ___

No subject
Hi, I have a coding problem. I have data pairs, and I want to calculate a parameter for the data pairs as a whole data set (so not using the information that thely are pairs) I am looking for bias in that certain parameter so I want to bootstrap these data pairs(!), and than calculate the parameter. I run into a coding problem. How should I define theta in order to resample the pairs, but than

Can boot return matrix?
Dear All, I have a function which takes a n x m matrix as an argument and returns an n x n matrix. I want to take bootstrap samples form the input matrix in the way as each row represent a multivariate observation, so each bootstrap sample would be an n x m matrix, and on each sample I want to calculate the n x n matrix. This task can be done with the sample function, but I would like to use

bca ci's and NaN's in boot.out
Dear All, I am trying to use the bca.ci function on a boot.out object which consists a few NaN's and I want to ignore those NaN's, and get a ci only for the "normal" values. boot.out$t has R number of values for 3000 different statistics, so when I use boot.ci(boot.out, index=i) and i happens to be a column in boot.out$t with some NaN's in there I get an error message.

apply with two matrixes
Hi, I have a function which does a certain task with two vectors, f1 <- function(a,b){body} I also have a list of matrixes (all with the same dim's), and for each column of each matrix in the list I want to use "f1", in such way that it gives the vector "a" in the first argument of "f1". The second argument of the function "b" also comes form a

boot&table
Hello, I want to bootstarp a sample, and I need table() for each sample taken, like if R=100, I need all 100 table(). It seems to mee that boot() works anly if you assing statistics, that gives you back one number, like mean. Although the ?boot/statistics says that it can be a vector containing statistics. table() gives an array, so it might work. Does anybody have an idea how? I konw it can be

R-1.9.1 on OS 10.2
Hi, I've been using R 1.7.1 but now I need to upgrade to R-1.9.1. Since it is not on the Fink tree yet I tried to install it from source to my sw library. The configuration runs fine, but make doesn't. Here is the error message I get: /sw/lib/libg2c.a(err.o) definition of common f(short, void, int, char) (size 4) /usr/bin/libtool: internal link edit command failed make[4]: ***

Problems with Mac OS X Beta 3 display?
Beyond a general problem with X11, that it sometimes doesn't display -especially when it is inactive for a while- new windows (like new terminal, R device, or emacs) and only the restart helps, I found a problem which might also be especially the X11's problem. >From an apple Terminal window, the following code (which is the first boot.ci example) works just fine.

Linear mixed models with custom link functions in R
Hello All, I am looking for an R library/function that allows the specification of a custom link function in a linear mixed model. I've been using glm() in library MASS to fit fixed-effect models with a custom link but my study design demands mixed models. Any suggestions on the best R library/function to achieve this would be greatly appreciated. I have tried, to no avail, to

Threshhold Models in gnlm
Hello, I am interested in fitting a generalized nonlinear regression (gnlr) model with negative binomial errors. I have found Jim Lindsay's package that will do gnlr, but I have having trouble with the particular model I am interested in fitting. It is a threshhold model, where below a certain value of one of the parameters being fitted, the model changes. Here is a sample: Cones:

multiple bases to decimal (was: comparing two matrices)
Hi again, I was contemplating the solution using base 3: set.seed(3) mat2 <- matrix(sample(0:2, 15, replace=T), 5, 3) Extracting the line numbers is simple: bases <- c(3, 3, 3)^(2:0) # or just 3^(2:0) colSums(apply(mat2, 1, function(x) x*bases)) + 1 [1] 7 23 25 8 1 The problem is sometimes the columns have different number of levels, as in: mat1 <- expand.grid(0:2, 0:2,
