similar to: checking for executable files ... WARNING

Hi all, R-exts currently requests that package authors don't include copies of standard licenses: > Whereas you should feel free to include a license file in your source distribution, please do > not arrange to install yet another copy of the GNU COPYING or COPYING.LIB files but > refer to the copies on https://www.R-project.org/Licenses/ and included in the R distribution > (in

I've changed to Mercurial for my working copies of survival for a number or resons not relevant to this post. When I do R CMD check, I get some warnings about certain files in the .hg directory with odd names. I've added the following 2 lines to my .Rbuildignore file without effect ^\.hg$ ^\.hg.* I'm not a Perl user so perhaps I'm reading the help page wrong. Any pointers? This

It would be really nice if R warned you when packages had conflicting methods. For example (and this took me a couple of hours to track down), RMySQL and RPostgreSQL both define setMethod("print", "dbObjectId"), so that: library(RMySQL) getMethod("print", "dbObjectId") library(RPostgreSQL) getMethod("print", "dbObjectId") Obviously

Is there really a need for these complications? Packages emitting this warning are broken by definition and should be fixed. Perhaps we could "flip the switch" in a test environment and see how much havoc is wreaked and whether authors are sufficiently responsive?

I was trying, on a Linux system, to get a .Rbuildignore file to work. After far too long, I found the problem was the <CR><NL> line endings in the .Rbuildignore file -- I had originally created it on a Windows system, and emacs in Ubuntu was politely hiding that fact from me. The patterns didn't work to exclude files because it was trying to match filenames to patterns like

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, Would someone mind pointing to me to the inspiration for the use of the L suffix to mean "integer"? This is obviously hard to google for, and the R language definition (https://cran.r-project.org/doc/manuals/r-release/R-lang.html#Constants) is silent. Hadley -- http://hadley.nz

But you can easily fall back to R from within Julia; see http://juliastats.github.io/RCall.jl/latest/ On Aug 5, 2016 1:27 PM, "Hadley Wickham" <h.wickham at gmail.com> wrote: > No. > > Hadley > > On Fri, Aug 5, 2016 at 11:12 AM, Kenny Bell <kmbell56 at gmail.com> wrote: > > Is it conceivable that Julia could be ported to use R syntax in a way > that

Is it conceivable that Julia could be ported to use R syntax in a way that would allow the vastly larger numbers of R programmers to seamlessly switch? Or equivalently, could an iteration of R itself do this?

Should the following two functions should always give the same result, except for possible differences in the 'call' component of the warning or error message?: f0 <- function(x, y) x || y f1 <- function(x, y) if (x) { TRUE } else { if (y) {TRUE } else { FALSE } } And the same for the 'and' version? g0 <- function(x, y) x && y g1 <- function(x, y) if

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?

This is admittedly minor, and you shouldn't have repeated names in a data frame anyway, but: df <- data.frame(1:3, 1:3, 1:3) # Ok setNames(df, c("x", "y", "")) # Not ok setNames(df, c("x", "", "")) Hadley -- http://hadley.nz

I have some questions about building packages in Windows when using .Rbuildignore . The part of the process that is of interest here is the part that creates the source tree from the tree that contains the .Rbuildignore file. That is, the part of the process that does a build of the original tree creating a .tar.gz and then extracts this file into a source directory that can be used by check,

I suspect this will have suboptimal performance since the TRUEs will get recycled.
