All: I apologize as I think I had this problem before, and misplaced my notes on the solution. I just tried to upgrade my version of R on a Redhat Linux computer. I downloaded and ran the rpm for R...

Hi there, When I am using the png() function as the following to generate a png file on Mac OSX Tiger, I found that the bit depth is 32. But I want a 24 bit depth png. What should I...

Sorry: I should have reproduced the "problem" with a simple example. I do this below. I think there is likely a switch I can change using par, but don't know what it is. The problem is the tick marks...

Hello, I have a number of files output1.dat, output2.dat, ... , output20.dat, each of which monitors several variables over a fixed number of timepoints. From this I want to create a data frame which contains the mean value between...

Like a couple of other posters in the past year, I was seeing R 2.8.1 segfault in the foreign package on my Solaris 10 Intel system: > library(foreign) *** caught segfault *** address fe1d5c70, cause 'invalid permissions' Traceback: 1: .C...

All: I am trying to use gam in a scatterplot smoothing problem. The data being smoothed have greater 1000 observation and have multiple "humps". I can smooth the data fine using a function something like: out <- ksmooth(x,y,"normal...

Dear list, I'm new to R, please bear with my silly questions. I'm trying to get an understanding of why the results I get from a call to hist() are not as I thought I would get. When...

Good morning R-help, I have an idiot question: I would like to use getSrcDirectory() and friends to allow me to identify where an R file has been called from when invoked using Rscript. If I understand the documentation correctly...

running R 1.4.1 on MAC and 1.2.2 on Linux When I use run binom.test with small N the results are a little perplexing to me >binom.test(9,20,p=0.5) gives the below...

Would the "predict" routine (using 'newdata') do what you need? Cliff Long Hollister Incorporated On Wed, Aug 12, 2009 at 4:33 AM, Jacob Nabe-Nielsen<jacobnabe at me.com> wrote: > Dear List, > > Does anyone know how to simulate data...

All: I have a matrix, X, with a LARGE number of rows. Consider the following three rows of that matrix: 1 1 1 1 2 2 3 3 1 1 1 1 3 3 2 2 3 3 2 2...

Hi all I am running a simple random intercepts model using lme4 on approximately 70,000 observations, with 250 clusters. The code looks like glmer(Y~x1+x2+x3+x4+x5+x6+x7+x8+x9+(1|clusdID), data=dt1, family...

Hello I'm new to using mixed models in R. Thus far I've been using MLwiN. I am trying to duplicate the results in MLwiN of a logistic mixed effects model. At the moment I have no covariates, and...

Greetings, I confess to being new to R, which I am exploring for some simulation modeling purposes. I am a long time programmer in PHP. I am having some trouble getting over the "steep learning curve" with some very basic...

Hi guys, I've got a question about the API mkchar(). I have met some difficulty in parsing utf-8 string to mkchar() in R-2.7.0. I was intending to parse an utf-8 string str_jan (some...

Hi, Ben, Could you take a look at your .../R-2.5.0/bin/SHLIB? This is what packages use to build their shared libs. This script is auto-generated based on R-2.5.0/src/scripts/SHLIB.in...

Hello I would like to extract the data for the posterior distribution for a random effect in MCMCglmm. Using the example in the tutorial: data(Traffic) prior <- list(R = list(V = 1, nu = 0.002), G = list(G1 = list(V...

Hi R users, I need to apply a function on a list of vectors. This is simple when I use functions that returns only one numerical value such as 'mean' or 'variance'. Things get complex when I use functions returning...
