R-users, My question is related to earlier posts about benefits of quadcore over dualcore computers; I am trying to setup a cluster of windows xp computers so that eventually I could make use of 10-20 cpu:s, but for learning how to do this, I am playing around with two laptops. I thought that the package snow would come handy in this situation, but to use snow, I would probably need to install

I have this problem with R 2.6.1 and 2.7.1 (have not tried others) running on Windows XP: Html help has wrong links to help files. The index.html is correctly found from file:///C:/PROGRA~1/R/R-26~1.1/doc/html/index.html as well as the search engine file:///C:/PROGRA~1/R/R-26~1.1/doc/html/search/SearchEngine.html However, when I search for, say, "paste", I will be pointed to

Hello, I have the TCl/Tk command "tkmessageBox(titel="",message="x",icon="question",type="okcancel")" in my R script. Now I want to perform some operation in relation to the user's choice, something like "if (okpressed) xxx else yyy" What values does this command give and how are they used? Thank you, Richard -- Richard M?ller -

Dear all, Is there any method in R to find all possible nonnegative integer solutions to the linear equation with unit coefficients as follow: X1+X2+...+Xk=N Thank you, Amin Zollanvari

The 'NMF' package implements a number of standard algorithms to perform Nonnegative Matrix Factorization. It also provides a flexible framework to easily test and develop new methods, as well as a layer to work with Bioconductor objects. The package is available from CRAN. Feedbacks are welcome. -- Renaud Gaujoux Computational Biology - University of Cape Town South Africa

On a CentOS 7 machine, I am at a loss with respect to an inability to run a full R CMD check as anything involving tex files ends in tears. We followed the README at CRAN and installed a large number of tex-live packages on this machine. But when a manual is created, we end up with what follows below. Here, I chopped some of the error messages, the key seems to be 'Insufficient extension

Full_Name: Kjetil Kjernsmo Version: 1.1.1.1 (patched the rpois :-)) OS: osf4.0e Submission from: (NULL) (129.240.28.227) Dear all, I have just gotten through a debugging session of my code, being confused for a few days. I sent what I thought was a straightforward matrix to chisq.test() and once in a while got the error message: > chisq.test(t2) Error in chisq.test(t2) : missing value where

Dear all, I would like to know if there is a function for sorting a data.frame based on one column. sort() does it for a single vector but not for the whole data. order() does it if there are relations between the columns but in my case it is simply a data.frame. Further, I would like to plot other data, pop.size<- c(800, 800, 1500, 1000, 158, 300, 740, 250, 2000, 1500, 250, 700)

Dear all, I'm using zeroinfl() from the pscl-package for zero inflated Poisson regression. I would like to calculate (aproximate) prediction intervals for the fitted values. The package itself does not provide them. Can this be calculated analyticaly? Or do I have to use bootstrap? What I tried until now is to use bootstrap to estimate these intervals. Any comments on the code are welcome.

A question about the inner workings of glm() and dpois(): Suppose I call glm(y ~ x, family=poisson, weights = w) where y contains NON-INTEGER (but still nonnegative) values. (a) Does glm() still correctly maximise the weighted Poisson loglikelihood ? (i.e. the function given by the same formal expression as the weighted loglikelihood of independent Poisson variables Y_i except that the

Dear R helpers, running the following code of a glm model of the family poisson, gives predicted values < 0. Why? library(MASS) library(stats) library(mvtnorm) library(pscl) data(bioChemists) poisson_glm <- glm(art ~ fem + mar + kid5 + phd + ment, data = bioChemists, family = poisson) predicted.values = predict(poisson_glm) range(predicted.values) Thank you in advance for any hints.

Hi all, The function h below is a function of c and it should be a monotone increasing function since the integrand is nonnegative and integral is taken from c to infinity. However, as we can see from the plot, it is not shown to be monotone. Something wrong with the usage of integrate function? Thanks so much for your help. Hanna h <- function(c){ g <- function(x){pnorm(x-8.8,

Hi all, I'm trying to write a script that changes all negative values in a data frame column to a small positive value, based on the the minimum value of the column. However, I get the following error: Error in if (x[i] < 0) { : argument is of length zero As well, I would "minimum" to be the smallest of the non-negative values...
