..."as.logical" So I thought I'd upgrade lme4 to the latest version, but unfortunately the compilation fails - perhaps there's a missing #include: R CMD INSTALL -l ~/usr/lib/R lme4_0.99875-8.tar.gz * Installing *source* package 'lme4' ... ** libs gcc -std=gnu99 -I/home/dreitter/usr/lib/R/include -I/home/dreitter/ usr/lib/R/include -I/usr/local/include -I"/home/dreitter/usr/lib/R/ library/Matrix/include" -fpic -g -O2 -c glmer.c -o glmer.o glmer.c: In function ???internal_Gaussian_deviance???: glmer.c:185: error: ???CHM_SP??? undeclared (first use in this fu...

...de. There is a good overview by Xianhong Xie here: http://cran.r-project.org/doc/Rnews/Rnews_2005-2.pdf Unfortunately, the article points out that some restrictions of Condor preclude us from running R in the standard universe. Does anyone know if this can be overcome? Thanks David -- David Reitter - ICCS/HCRC, Informatics, University of Edinburgh

It's probably a beginner's question: How do I show text in boxes? That is, can I specify a background color for text output with text() ? The following doesn't work as I would expect: text(labels="123", 50, 0.5, bg="green") I've experimented with legend(),which will make the box too wide, and also with rect(), which doesn't know the extent of the text

In this example, where a header line in a file has an incorrect number of row names (28 instead of 29), I get the error message "duplicate row.names are not allowed". However, I cannot not find any

Using the Hmisc package, I tried to create an xYplot (single panel only) and was confused to find that I could not add anything else to the plot (abline, lines, etc.). Thankfully, [1] points out panel functions. This works as expected for panel.abline, but as soon as I'm using panel.lines (or llines or lpoints) from the "lattice" package (version 0.17-17 with R 2.8.1), it

I'm using glmmPQL, and I still have a few problems with it. In addition to the issue reported earlier, I'm getting the following error and I was wondering if there's something I can do about it. Error in logLik.reStruct(object, conLin) : Na/NaN/Inf in foreign function call (arg 3) ... Warnings: 1: Singular precistion matrix in level -1, block 4 (...) 4: "" The

I'm trying to use "predict" with a linear mixed-effects logistic regression model fitted with nlmmPQL from the MASS library. Unfortunately, I'm getting an error "non-conformable arguments" in predict.lme, and I would like to understand why. I have used the same call to "predict" with "glm" models without problems. I assume I'm doing

I'd like to briefly describe how I ended up working around this problem. The issue is that predict.lme
