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

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 ___

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. I

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

Does anyone know how to coerce a list to an array? I have a list with equal sized matrixes and I want to coerce it to a 3D array. Why is that that I cannot feed in equal sized matrixes as layers to an array even if I set dim 3? Thanks!

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

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.

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

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]: ***

Given an nxm matrix A I want to compute the nxm matrix B whose ij-th element is the sum of the elements of A lying on the diagonal that ends with element ij, i.e., b_ij = a_ij + a_(i-1)(j-1) + a_(i-2)(j-2) + ... In APL (which I no longer use), I would use the 'rotate' operator to derive an array whose columns are diagonals of the given array and then cumulate down columns. Is

I am trying to write an efficient function that will do the following: Given an nxm matrix, 10 rows (observations) by 10 columns (samples) for each row, test of all values in the row are greater than a value k If all values are greater than k, then set all values to NA (or something), Return an nxm matrix with the modified rows. If I do this with a matrix of 20,000 rows, I will be waiting until

Hello, I am trying to find a permutation test that works on a general nxm table. The data set is small enough to have cells with too small counts to make chi2-approximation invalid. If the table was a 2x2 contingency table I would like to use a Fsher exact test (fisher.test) but that wont work in this general table. Does there exist a general function for this test. Best regards, Magnus

Dear R listers, Just a simple question. If we say an nxm matrix (n>m) is full rank of m, does this mean that this matrix has linearly independent columns? They are the same definition or needs some proof? Thanks for your answer. Fred [[alternative HTML version deleted]]

Hello R community, I am using R for creating a model using optimization. I would like to ask if there is R-function/package for solving the problem below: Minimize sum(abs(exp^(Ai1 x1 + Ai2 x2 + ... + Aim xm - bi) - 1)), for each i = 1, ..., n. subject to Ai1 x1 + Ai2 x2 + ... + Ajm xm - bi <= c, where c is a scalar. (x is a vector of variables, A is nxm matrix, b is a vector)

Hi. I am aware of three different R packages for linear programming: glpk, linprog, lpSolve. From what I can tell, if there are N variables and M constraints, all these solvers require the full NxM constraint matrix. Some linear solvers I know of (not in R) have a sparse matrix input format. Are there any linear solvers in R that have a sparse matrix input format? (including the

Hi everyone! I'm trying to teach myself R in order to do some data analysis. I'm a mathematics student and (only) familiar with matlab and latex. I'm working trough the "official" introduction to R at the moment, while simultaneously solving some exercises I found in the web. Before I post my (probably stupid) question, I'd like to ask you for some general advice. How do

Dear All, I have problem installing the 'kinship' package. I used the 'install.packages' from R command line and had no problem installing other packages before.

Dear All, I need to write 'n' functions on 'm' variables. The functions should be constructed according to the values of an (nxm) matrix of '1/0' values as follows. For example, if row1 is equal to ,say [1 0 .......0 0] then f1 <- (1+x1) if row 2 is equal to, say [1 1 1 0...0 1] then f2 <-(1+x1)*(1+x2)*(1+x3)*(1+xm) if row n is equal to [0 1 0 1 1 0 ..... 0] then
