I don't know the right computer science words for this question, I'm afraid. Apology in advance. How do you find your way around in somebody else's code? If the user runs a specific command, and wants to know how the data is managed until the result is returned, what to do ? I've tried this manually with tools like mtrace and browser. This is a bit frustrating because the

I have some questions about 1. nomenclature, 2. recommended file locations and 3. overall procedure related to creating packages. To the extent that it matters, examples here relate to Windows XP R 2.0.1 beta. The questions are interspersed and prefaced with ***. My understanding is that there are actually 6 forms of a package that one should use in package development: 1.

Hello. I have what I know to be a simple question, but never having done anything like this it is pretty tough. I'm trying to write an R package. I have a collection of functions that I loaded into R and then used package.skeleton(). After editing everything in the resulting folder, call it NewPackage, I tried to follow along with some instructions I found for Windows users. I installed

Dear List, I’m doing my first baby steps towards developing own R Packages and ran into the following problem: R CMD check mypackage works fine (no errors, no warnings) R CMD build mypackage works fine (no errors, no warnings) R CMD INSTALL –library=”C:\R\R-2.11.1\library” “something\mypackage\mypackage_1.0.tar.gz” works fine (no errors, no warnings) However, when I try loading the

I imitated predict.glm, my thing worked, now I need to revise. It would help me very much if someone would explain predict.glm line 28, which says object$na.action <- NULL # kill this for predict.lm calls I want to know 1) why does it set the object$na.action to NULL 2) what does the comment after mean? Maybe I need a pass by value lesson too, because I can't see how changing that

Hi, I'd like to know whether there is a package (or more, of course) regarded as a good example that could be used also as an instructional tool for newcomers to R extensions development.

Yesterday I uploaded new rockchalk_1.8.97. Then I received email saying that I needed to confirm the submission. Here's the message. Dear Paul E. Johnson Someone has submitted the package rockchalk to CRAN. You are receiving this email to confirm the submission as the maintainer of this package. To confirm the submission to CRAN, follow or copy & paste the following link into your

I'm aware R-devel no longer includes zlib. This works find on up-to-date Linux systems. On the older Centos 6 cluster at KU, they have zlib tool old for R-devel. The R-devel configure fails thus: checking if zlib version >= 1.2.5... no checking whether zlib support suffices... configure: error: zlib library and headers are required In other software, I've seen this kind of thing, so

I've been doing some consulting with students who seem to come to R from SAS. They are usually pre-occupied with do loops and it is tough to persuade them to trust R lists rather than keeping 100s of named matrices floating around. Often it happens that there is a list with lots of matrices or data frames in it and we need to "stack those together". I thought it would be a simple

I hope you are doing well. For me, this was an unexpected problem. I've hoped for quite a few wrong things today, but I'm only asking you about this one. Why does ifelse(1, list(a, b, c), list(x, y, z)) return a list with only a, not list(a, b, c) as I hoped. I wish it would either cause an error or return the whole list, not just the first thing. Working example: > x <- 1 >

I'm writing to ask for a policy exception, or advice on how to make this package CRAN allowable. http://rweb.quant.ku.edu/kran/src/contrib/portableParallelSeeds_0.9.tar.gz Yesterday I tried to submit a package on CRAN and Dr Ripley pointed out that I had not understood the instructions about packages. Here's the part where the R check gives a Note * checking R code for possible

I'm writing to ask if R Core would make file.exists more Windows tolerant when the argument has a trailing slash. This has been discussed by users a few times here, I know it is not a new topic. But it is not a solved problem, yet. I acknowledge that CRAN packages exist which fix this by replacing file.exists(), but it seems more elegant to me to fix the problem in R itself. R Core goes to

I'd like to create a small "local" repository that would be used to install a package for a class of students at their home. I don't want to upload it to CRAN, as I don't think it should be disseminated at that level. What I'd like to do is: > where="http://mysite.com/" > install.packages("mypackage",contriburl=where) When I try this, (after

I'm attaching a file foo.Rnw and I'm hoping some of you might run it through your R & latex systems to find out if the double-quotes in typewriter font turn out as black boxes (as they do for me). If you don't use Sweave, but you have a system with a working version of R and LaTeX, the file gives the instructions you need to use to process the file. The The file itself explains

I want to write an R help example that throws up 2 graphs in separate windows, for comparison. In Linux I plot one, then run x11() to spawn a new on-screen device. Is there some generic equivalent so I can write an example that will work for Windows and Mac users as well? If there is none, don't you think it would be fun if there were? pj -- Paul E.

I'm looking for an R mentor. I want to propose a change in management of plot options xlim and ylim. Did you ever want to change one coordinate in xlim or ylim? It happens to me all the time. x <- rnorm(100, m=5, s=1) y <- rnorm(100, m=6, s=1) plot(x,y) ## Oh, I want the "y axis" to show above x=0. plot(x,y, xlim=c(0, )) ##Output: Error in c(0, ) : argument 2 is empty

Here's my little discussion example for a quadratic regression: http://pj.freefaculty.org/R/WorkingExamples/regression-quadratic-1.R Students press me to know the benefits of poly() over the more obvious regression formulas. I think I understand the theory on why poly() should be more numerically stable, but I'm having trouble writing down an example that proves the benefit of this. I

This is a basic Windows system administrator problem, asked by a Linux guy who is helping out in a Windows lab. I want to keep R packages up to date on MS Windows 7 with a job in the "Task Scheduler". I have an R program that I can run (as administrator) that updates the existing packages and then installs all the new ones. I do not understand how to run that in a dependable way in
