similar to: capturing warnings using capture.output

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

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.

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

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 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

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

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

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?

The suppressMessages and suppressWarnings functions currently suppress all the message or warnings that are generated by the input expression. The ability to suppress only specific messages or warnings is sometimes useful, particularly for cases like file import where there are lots of things that can go wrong. Suppressing only messages that match a regular expression has rightly been rejected

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

AFAIK this is the way it works on Windows.

I would like to preserve the values of all the arguments to a function in a results object. foo <- function(a, b=1) .... foo(x, 3) match.call() looks promising, but it records that a is x, while I want the value of x (in the calling frame). Also, if the invocation is foo(x), then match.call doesn't record that b is 1. So I tried this (inside the function definition): myargs <-

I am working with some large text files (up to 16 GBytes). I am interested in extracting the words and counting each time each word appears in the text. I have written a very simple R program by following some suggestions and examples I found online. If my input file is 1 GByte, I see that R uses up to 11 GBytes of memory when executing the program on a 64-bit system running CentOS 6.3. Why is
