Dear All, I am trying to put some Confidence intervals on some regressions from a linear model with no luck. I can extract the fitted values using 'predict', but am having difficulty in getting at the confidence intervals, or the standard errors. Any suggestions would be welcome Cheers Guy Using Version 2.1.0 (2005-04-18) on a PC vol.mod3 <-

Dear all, I an running R on a Windows 2000 machine (1.5Gb RAM) and am trying to load the lme4 package, however, whenever I attempt to load the library "lme4" I get the following error message I have installed lme4 and Matrix locally from the zip file with no problems.

Dear R users I am using GLMMpql to analyse some nested negative binomial response data. How do I summarise the significance of my main effects? For example, in a standard linear mixed model (lme), I would use anova.lme to obtain an F statistic and P value for each of my main effects: how do I achieve a similar goal using GLMMpql? many thanks Sarah Richardson Sarah Richardson Plant

Hello together, Is there a tool to test the statistical differences between parameter estimates of a nlsList fit? I fitted degradation data using the nlsList method and want to find out whether derived rate constants are significantly different from each other at the grouping factors soil and temperature.

Hi all. I have an issue that I cannot resolve. I am trying to read in lots of data that are stored in xml files. But after I read them in and copy the relevant data, then remove the document etc, it doesn't free up the memory. When I monitor it in windows task manager the memory usage just climbs with each iteration until R crashes. I can replicate the problem with the small example:

Hi, It feels like I should be able to do something like: R CMD INSTALL lib='/usr/lib64/R/library' repos='http://proxy.url/cran' package We have a bunch of servers (compute nodes in a Rocks cluster) in an isolated subnet, there is a basic pass-through proxy set up on the firewall (the head node) which just passes HTTP requests through to our nearest CRAN mirror. when using

Hi list, In a function I am writing, I need to extract the dimension names of an array. I know this can be acheived easily using dimnames() but my problem is that I want my function to be robust when the number of dimensions varies. Consider the following case: foo <- array(data = rnorm(32), dim = c(4,4,2), dimnames=list(letters[1:4], LETTERS[1:4], letters[5:6])) # What I want is to extract

I am analyzing data from an experiment with two factors: Carbon (+/-) and O3 (+/-), with 4 replicates of each treatment, and 4 harvests over a year. The treatments are assigned in a block design to individual Rings. I have approaches this as a repeated measures design. Fixed factors are Carbon, O3 and Harvest, with Ring assigned as a random variable. I have performed repeated measures analysis

Full_Name: Dave Ramsey Version: 1.8.0 OS: win2000 Submission from: (NULL) (202.27.240.6) there is a bug in extractAIC.survreg in library MASS. A survreg model object has no component called "residuals". Hence n <- length(fit$residuals) returns 0 resulting in errors workaround: replace n <- length(fit$residuals) with n <- length(residuals(fit)) ### sorry: error

R Experts I'm currently using an S+ script of the following format and would like to convert it to R. The script opens a graphsheet with an associated name, plots something (in this case a boxplot) and then exports the contents of the graphsheet of the assigned name to an EMF file. I've been looking for something in R that would work the same way but to no avail. Could someone

Hello, I am trying to convert the following command from SPLUS to R: graphsheet(pages = TRUE) Does anyone have an idea what is the equivalent in R?

I'm using R 2.0.1 in a class I teach, with most students working under windows XP. We have a data frame with the first column containing the factor "site," and five water-quality variables at each site. As one part of exploring these data, I'd like the students to run by(ourdata,site,pairs). When I try that, however, the pairs plots for the first 10 sites scroll past, and

Dear All, I am new to R and can see it is a very powerful and versatile system for programming and statistical analysis. Say I have written a simple function and want to use it on a regular basis. I have the file as a text file say 'c:\R-funcs\func.txt' how do I get R to find it on the hard disc or alternatively where is the default location for looking up functions where I can place

Dear Friends, Yesterday I posed a question to the list concerning the possibility of doing animation examples in R. Here is an example S-Plus (4.5 for Windows ) that I wrote to illustrate my problem. If I try this in R (comment out the graphsheet and guilocator calls) I don't see my results until after the function has iterated through the 100 trials. I would like to plot each iteration.

Dear friends, I am trying to port a collection of S-PLUS teaching functions over to R. Several of my functions use animation. Animation in S-PLUS is not ideal, but can be accomplished with a call to guiLocator (this forces the program to print to the graphsheet rather than wait until the function has completed all calculations). Does anyone know if there is a trick that will enable me to

I'm running samba 2.2.2-6 on a redhat 7.2 box running 2.4.9-7 kernel... I'm trying to upload printer drivers from a Windows 2000 client. I've followed the instructions in the samba howto collection. I've created the print$ share, created the printer directory and subdirs, and made sure they are writeable by me. I put myself in the write list and the printer admin list.

Hi. I''m migrating to shorewall(6) mgmt of my various firewalls. Simple configs have been easy with the great docs. I''ve got a slightly more convoluted config, and have gotten ''lost'' in config''ing a SNAT/DNAT/NAT + DMZ + Xen Host/Guest set up with Static IP/29. Having some challenges wrapping my head around the ''best'' Shorewall

Is there a set of R expressions that has the same effect as the following set of S-Plus 2000 expressions: graphsheet(format="printer", orientation="landscape") par(mfrow=c(2,2)) plot(x1, y1) plot(x2, y2) plot(x3, y3) plot(x4, y4) dev.off() # one page of landscape plots sent to printer I am having trouble with formulating the equivalent of the first line of the above in R.

Dear All, Many thanks to those who replied to my query about getting functions into "R". I have another problem that I hope is as easy to solve as the last one. I want to install the package Tree on my system and have no idea how to go about it.
