Hi all, What should you do when you rely on a data only package. If you just "Depend" on it, you get the following from R CMD check: Package in Depends field not imported from: 'hflights' These packages needs to imported from for the case when this namespace is loaded but not attached. But there's nothing in the namespace to import, so adding it to imports doesn't

Greetings! I could use some suggestions on how to proceed from where I am to where I want to go. I''m working on an app that collects info from the visitor and saves it to a file. The file can later be read in for update. To collect the info, the app presents a form with a set of checkboxes. The state of the checkboxes at initial presentation is controlled by a summary record that is

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

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?

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

I left out the warning - it's still there. The output object is malformed but either +.factor should prevent this or match() should check.

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

In case anyone is interested in reading (and maybe helping!) with a dsync redesign that's intended to fix all of its current problems, here are some possibly incoherent ramblings about it: http://dovecot.org/tmp/dsync-redesign.txt and even if you don't understand that, here's another document disguising as an algorithm class problem :) If anyone has thoughts on how to solve it, would

Same thing happens with S3 if you redefine print(). I thought that code was actually calculating the function to call rather than the symbol to use, but apparently not. Shouldn't be too hard to fix. luke On Tue, 30 Jun 2015, Hadley Wickham wrote: > On Tue, Jun 30, 2015 at 2:20 PM, Duncan Murdoch > <murdoch.duncan at gmail.com> wrote: >> On 30/06/2015 1:57 PM, Hadley

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?

Hi all, Is there a better to way to subset the ROWs (in the sense of NROW) of an vector, matrix, data frame or array than this? subset_ROW <- function(x, i) { nd <- length(dim(x)) if (nd <= 1L) { x[i] } else { dims <- rep(list(quote(expr = )), nd - 1L) do.call(`[`, c(list(quote(x), quote(i)), dims, list(drop = FALSE))) } } subset_ROW(1:10, 4:6) #> [1] 4 5 6

I get the same style of path as Hadley. This is on Windows 7 Home Premium with SP1. I start R by clicking on the R-2.31.0 icon. I'd assumed that it was a change that came with R-2.13.0!
