[R] passing arguments to multiple functions

Hi, I am writing a function and I want to pass arguments to a function I will call internally without having to specify all the possible arguments to pass. Usually I would use '...' but I want to do this for two functions that I will call, and the two functions do not take the same arguments. S

[R] NA in eigen()

Hi, I am using eigen to get an eigen decomposition of a square, symmetric matrix. For some reason, I am getting a column in my eigen vectors (the 52nd column out of 601) that is a column of all NAs. I am using the option, symmetric=T for eigen. I just discovered that I do not get this behavior

[R] Question about Sweave

Hi, I'm not sure if Sweave questions should go to the general list, but it seems to be part of the core R package without a separate maintainer. I am writing a tutorial for R in a latex file. I'd like to use Sweave, since this seems its ideal usage. The problem is that I want to purposefully p

[R] listing datasets from all my packages

Hi, I am using R 2.1.0 on Windows XP and when I type data() to list the datasets in R, there is a helpful hint to type 'data(package = .packages(all.available = TRUE))' to see the datasets in all of the packages -- not just the active ones. However, when I do this, I get the following message:

[R] name space of a package

I am trying to copy a R function (specifically "boot" of the boot package, but I don't think my problem is related to the specific function/package I'm using) and modify it slightly for my own use and/or understanding. For example, I want to understand why I'm getting an error from "func", so I

[R] sapply behavior
