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.

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

>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 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

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 I want to assign some variables into an environment, it seems natural to do something like e <- new.env() within(e, { x <- 1:5 y <- runif(5) } ) This throws an error, since within.environment doesn't exist.? I realise I can work around it using as.environment(within(as.list(e), { x <- 1:5 y <- runif(5) } )) Just wondering why I

...o R. In the end they either succeed with their muddling or give up, - but do not change the system.

Is there a complete list somewhere of the possible values for R's status, as returned by version$status? I know about these values: Stable: "" Devel: "Under development (unstable)" Patched: "Patched" Release candidate: "RC" Alpha: "Alpha" Are there any others that I've missed?

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

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. I think that the relevant line in the policies are: > When submitting a package to CRAN you should use the submission form at > http://CRAN.R-project.org/submit.html (and not send an email).

Today while running update.packages(ask = FALSE), R stopped to ask me a question: There are binary versions available but the source versions are later: binary source needs_compilation KernSmooth 2.23-13 2.23-14 TRUE mixture 1.2 1.3 TRUE Do you want to install from sources the packages which need compilation? y/n: update.packages calls

Hi, at the R prompt, is it possible to retrieve the last error (as in condition object of class "error")? I'm not asking for geterrmessage(), which only returns the error message (as a character string). I'm basically looking for a .Last.error or .Last.condition, analogously to .Last.value for values, which can be used when it is "too late" (not possible) to go back

One piece of feedback that I received at useR was that the assertive package is getting too big, and should be broken down into smaller pieces. I want to split the functionality into assertive.base, assertive.types, and a few others, then have the assertive package as a virtual package (suggestions for better terminology welcomed) that just imports and reexports the contents of the underlying
