Hi all, At RStudio, we're hosting our Introduction to R Workshop this May in two locations.

I'm always forgetting to update the date in DESCRIPTION. Would it be possible to add a warning to R CMD check if it's old? Hadley -- http://had.co.nz/

Dear all, I have been working on an idempotent version of apply, such that applying a function f(x) = x (ie. force) returns the same array (or a permutation of it depending on the order of the margins): a <- array(1:27, c(2,3,4)) all.equal(a, iapply(a, 1, force)) all.equal(a, iapply(a, 1:2, force)) all.equal(a, iapply(a, 1:3, force)) all.equal(aperm(a, c(2,1,3)), iapply(a, 2, force))

The problem is that the default print mechanism isn't calling methods::show() (or base::print() as Luke says), it's calling show() or print() in the

Hi all (but especially Kurt), Would it be possible to have a flag to R CMD check that warned on partial all matches, i.e. turning on: options( warnPartialMatchDollar = TRUE, warnPartialMatchArgs = TRUE, warnPartialMatchAttr = TRUE ) I think this is good practice for package code. I don't think it can currently be made part of the default (because sometimes the warnings come from

Hi all, Does anyone have any suggestions for debugging the execution of examples by R CMD check? The examples work fine when I run them from a live R prompt, but I get errors when they are run by R CMD check.

Jan and Hadley, There's also the issue of tests, vignettes, or examples requiring Suggested packages (one of the core applications of Suggests, in fact). These are all checked by R CMD check, so to ensure any package which should pass check would do so without suggested packages installed would require turning all of those checks off, which takes quite a few of the teeth out of R CMD check

Dear R team, Are suggested dependencies mandatory in context of `R CMD check` when using env var `_R_CHECK_FORCE_SUGGESTS_=FALSE`? Suggested dependencies are nice because are optional. But that feature often isn't valid when trying to run `R CMD check` on them. I would like to use `export _R_CHECK_FORCE_SUGGESTS_=FALSE`, which according to the comment in `tools/R/check.R`: > The

I am wondering if people on the list could recommend books that they have found helpful about programming concepts and style? I often find that students write R programs by copying existing code but could really benefit from the understanding of more general programming ideas. An example would be to avoid writing functions which attempt to modify their parameters. Another principle would be

Make the example print out Sys.getenv() and then manually inspect? Otherwise, you'll need to debug the code by adding print statements. Something clearly is not as you expect, so you need carefully empirically verify your assumptions about the inputs to and environment of the function.

Hi all, all.equal is generally very useful when you want to find the differences between two objects. It breaks down however, when you have two long strings to compare: > all.equal(a, b) [1] "1 string mismatch" Does any one know of any good text diffing tools implemented in R?

What do you prefer/recommend for double-banger function names: 1 scale.colour 2 scale_colour 3 scaleColour 1 is more R-like, but conflicts with S3. 2 is a modern version of number 1, but not many packages use it. Number 3 is more java-like. (I like number 2 best) Any suggestions? Thanks, Hadley
