Differences between package and library terminology
Just out of curiosity, what is the difference between the terms for package and library ? Why are we loading a package with the library() command ? If this is a case of RTFM, I would be happy to do so if pointed in the right direction. I have searched the FAQ and mail archives and only came up with http://tolstoy.newcastle.edu.au/R/help/05/02/12162.html but this still does not explain what is

Journal Quality R Graphs?
Hi! I have browsed the help archives but did not find anything on the subject: How to make publication quality graphs with R best? Is there some document about that topic out there? The problem is that the graphs look nice on the screen but when printed in black and white every color apart from black doesn't look very nice. Is there some guideline how to set color palettes and or fill

follow up on "[Rd] NAMESPACE & methods guidance, please" ( http://tolstoy.newcastle.edu.au/R/e4/devel/08/06/1901.html )
This is a follow-up on the discussion originally posted on the R-devel list ( http://tolstoy.newcastle.edu.au/R/e4/devel/08/06/1901.html ), as I have encountered the exact same issue mentioned in Martin's email. Here is a simplified version of my problem: ##================================================================= ## I created a package, say, "tmpA", with a NAMESPACE with

Still avoiding loops
Dear all, I have a matrix X with 47 lines and say 500 columns - values are in {0,1}. I'd like to compare lines. For that, I first did: for (i in 1:(dim(X)[1]-1)) for (j in (i+1):dim(X)[1]) { Y <- X[i,]+Y[j,] etc. but, since it takes a long time, I would prefer avoding loops; for that, my first idea was to add this matrix: X1=X[,rep(1:46,46:1)] to this one: res=NULL for (i in

Survey of "moving window" statistical functions - still looking f or fast mad function
Hi, First, let me thank Jaroslaw for making this survey. I find it quite illuminating. Now the questions: * the #1 solution below (based on cumsum) is numerically unstable. Specifically if you do the runmean on a positive vector you can easily get negative numbers due to rounding errors. Does anyone see a modification which is free of this deficiency? * is it possible to optimize the

MICE for Cox model
R-helpers: I have a dataset that has 168 subjects and 12 variables. Some of the variables have missing data and I want to use the multiple imputation capabilities of the "mice" package to address the missing data. Given that mice only supports linear models and generalized linear models (via the lm.mids and glm.mids functions) and that I need to fit Cox models, I followed the previous

R "sumo" package suggestion
r-help: I have an R package suggestion. After spending several hours the other day installing about a dozen packages, I had an idea. In xemacs, there is a "sumo" package which allows me to install a large bundle of xemacs packages at one time (about a 120 modes including ESS). I think R should have a similar bundle. It would be so much easier than hunting/downloading/installing.

multi-argument returns
Dear R users, I have multi-argument returns in a function and I am warned by the program they are deprecated.

stable backport apt problem (solved)
Hello, I started writing this email to describe a problem, then fixed it, so I'll display my ignorance anyway in case other people have a problem with it. What happened was that I could get apt-get to upgrade the documentation packages, but not the others. What I think was the problem was some remaining r-cran-* packages that are now in r-recommended. These seemed to be blocking the

Failing to install R-2.4.0 on FC4
Hi everyone, Firstly, I'm sorry for the cross-post. I re-read the posting guide and it appears my question is more related to r-devel.... (i think :-) ) I downloaded the source code available at: http://cran.fhcrc.org/src/base/R-2/R-2.4.0.tar.gz to a linux machine (Linux 2.6.11-1.1369_FC4smp #1 SMP). I successfully configured and compiled it, which means I'm able to run it from the
