Hi all, How to convert following simple python script to R if x in a_list: print x OR simply, how to test if a vector contain a value? Thank you in advance, Hyunchul [[alternative HTML version deleted]]

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

AFAIK this is the way it works on Windows.

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

I'm trying to convert the following text into an ordered list, but when it hits the fourth level nested list, the list items aren't converted into <li>'s. Is there a limit to how far you can nest a list? * COURT INFORMATION * Opinions &amp; Orders * Administrative Orders * Opinion Search * Supreme Court * Superior Court *

Hello all, hope all is well this maybe outside of libvirt-users.... Can you nest macvtap devices to ultimately receive a real routable ip on the nested vm? I have a nested vm up and running. Both vm and nested vm are centos 7 on arch linux host. The first vm uses a macvtap in bridge mode receives dhcp from an external dhcp server. I start the second vm and dhclient hangs and never receives an

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 just had a manuscript returned with the biggest problem being the analysis. Instead of using principal components in a regression I've been asked to analyze a few variables separately. So that's what I'm doing. I pulled a feather from young birds and we quantified certain aspects of the color of those feathers. Since I often have more than one sample from a nest, I thought I
