similar to: .S4methods inconsistent behavior with methods, .S3methods

Great spot, thanks Mark. This really ought to appear somewhere in the ?Quotes help page. Having a warning under Windows might be nicer behaviour than silently returning the wrong value too.

Here's a data frame with some Unicode symbols (set intersection and union). d <- data.frame(x = "A \u222a B \u2229 C") Printing this data frame under R 3.2.0 patched (r68378) and Windows 7, I see d ## x ## 1 A <U+222A> B n C Printing the column itself works fine. d$x ## [1] A ? B ? C ## Levels: A ? B ? C The encoding is correctly UTF-8.

>From the Details section of ?capture.output: Messages sent to stderr() (including those from message, warning and stop) are captured by type = "message". Note that this can be "unsafe" and should only be used with care. Capturing messages works as expected: capture.output(message("!!!"), type = "message") ## [1] "!!!" Capturing warnings

If I want to use with inside a loop, it seems that next gets confused. To reproduce: for(lst in list(list(a = 1), list(a = 2), list(a = 3))) { with(lst, if(a == 2) next else print(a)) } I expect 1 and 3 to be printed, but I see [1] 1 Error in eval(expr, envir, enclos) : no loop for break/next, jumping to top level Is this a) by design, or b) a bug, or c) a thing that is rare enough that I

If you set the "digits17" control option in deparse, you get a lot of unnecessary space in the representation of complex numbers. > deparse(0 + 0i) [1] "0+0i" > deparse(0 + 0i, control = "digits17") [1] "0 + 0i" As far as I can tell, the logic for this comes from this piece of /src/main/deparse.c: if (TYPEOF(vector) == CPLXSXP

I've just been trying to post-process some R-created heatmaps using Inkscape, but I can't get them to display correctly in that software. To reproduce: library(grid) r <- as.raster(matrix(runif(25), 5, 5)) pdf("test.pdf") grid.newpage() grid.raster(r, interpolate = FALSE) dev.off() This figure should be a five by five block of grey squares. This is what I see in the R GUI

If I type a character using \U syntax that has more than 4 digits, I get the wrong character. For example, "\U1d4d0" should print a mathematical bold script capital A. See http://www.fileformat.info/info/unicode/char/1d4d0/index.htm On my machine, it prints the Hangul character corresponding to "\Ud4d0" http://www.fileformat.info/info/unicode/char/d4d0/index.htm It seems

AFAIK this is the way it works on Windows.

Hi, I was trying to get a list of S3 method for a given generic, along with the package in which they are defined, and I came across what looks like an issue in the data.frame returned in attribute 'info'. The column 'from' mostly gets the value "registered S3method for ..." except for visible methods. Is this the expected behavior? See code and output below. Thank you.

I recently tried to submit a package to CRAN using the release function in the devtools package and got the response: > The policies asked you to use the webform: do so in future.

Hi, There seems to be a problem with setGroupGeneric() from package 'methods'. The symptoms are somewhat erratic, in the sense that small changes may lead to any of the following behaviours. 1.Package works without problems on Windows and installs on Linux but gives error when loaded with library(). 2.Package installs on both systems and gives error when loaded on any of them. 3.

Richie, The R language definition [1] says (10.3.1): \Unnnnnnnn \U{nnnnnnnn} (where multibyte locales are supported and not on Windows, otherwise an error). Unicode character with given hex code ? sequences of up to eight hex digits. Best, Mark [1] http://cran.r-project.org/doc/manuals/r-release/R-lang.html http://www.markvanderloo.eu

i often find myself having a list of similarly-classed S4 objects and needing a list containing a particular extracted slot from those objects. so i did the following: > setMethod("slot", signature(object = "list"), + function(object, name) + lapply(object, function(i) slot(i, name))) Creating a new generic function for 'slot' in '.GlobalEnv' [1]

Dear all, I'm experiencing an unusual installation error for one package. Could anyone suggest how I can best investigate this from here please? I'm sorry this isn't very much to go on. Hopefully someone can point me in the right direction. The problem seems to be my library. It is large (3,418 packages) and I'd like to avoid rebuilding it, if possible. All packages are up to

I'm having an issue with occasionally slow-running calls to normalizePath. If the path is a non-existent UNC path, then normalizePath sometimes takes 6 or 7 seconds to run, rather than its usual few microseconds. My big problem is that I can't reliably reproduce this across machines. The example below generates one or two slow runs out of 10000 on my Windows machine. I haven't been

Hello, Besides the problem with using "names," one has a similar problem using ".Data" together with "VIRTUAL." Consider the top of p. 295 of the green book. This should work (I had to change "structure" to "junk" because "structure" is a sealed class definition): setClass("junk",
