Any idea why CHAR(asChar(STRING_ELT( produces NA whereas CHAR(STRING_ELT( gets a pointer to a string? It's generally expected that STRING_ELT should already be a character, but why the coercion does not work? Here is a simple example (consistent over R2.5.1-R2.6 rev 42284, I didn't check earlier versions, but it used to be different in 2.4): install.packages("inline")

Hey all, new R user and first timer here. I've been using getGraphicsEvent() on an X11-Xlib device in a kind of interactive loop, and would like to be able to stop it from printing newlines in the console when I don't actually want to print a prompt. Even an empty "" value still causes a newline right now. To not break any code that depends on this behavior, I figured getting

Hello Everyone, I have been reading this mailing list for a while and am impressed with the generous help that many here are eager to provide. Perhaps someone will be able to shed some light on a configuration issue I am having. Thank you in advance for any assistance. First, system setup details: #System Setup# * OS: Fedora Core 4 running in a VMWare box on Windows XP * Database: MS SQL

Hello - I am making a first attempt at writing a simple C++ routine to print out R objects (this is a simple proof-of-concept as part of a larger package development). The relevant C++ routine is as follows: void Rwrite(SEXP fd, SEXP msg) { int *ofd = INTEGER(fd); const char * omsg = CHAR(asChar(msg)); printf("[%i] %s",*ofd,omsg); } And the corresponding interface in R is as

hi, i have this in my code Article.find_by_contents("#{searchstring} +city:#{passedincity}") well that returns to me only articles that belong to whatever the user selected in city. now is it possible to search the grandparent? for example class country has_many states class states has_many cities belongs_to country class city belongs_to states ...... i would like to search

Hello, The current xfig device lacks the functionality to set the textspecial flag and use the defaultfont in xfig. This is necessary when you want to export to xfig and use interpreted text (e.g., $ \frac{1}{e}$ gets interpreted by latex). The attached patch adds this functionality. Why would you like to do this? - Use math in labels (e.g., name your variables $r_{xy}$, do a

Hello, in "Writing R Extensions" I found the following stuff: "Note that these coercion functions are not the same as calling as.numeric (and so on) in R code, as they do not dispatch on the class of the object. Thus it is normally preferable to do the coercion in the calling R code." ( Writing R Extensions, 2011-04-13, page 100 ) What is meant by

Full_Name: G. Grothendieck Version: R version 2.1.0, 2005-05-14 OS: Windows XP Submission from: (NULL) (216.59.254.207) This code: > plot(1:10) > text(5,5,lab=expression(italic(22*"33"))) has the effect of italicizing 33 (which is a character string) but not 22 (which is not). I would have thought that both, not just 33, would be italicized. I had previously posted about this

Shouldn't Rf_mkString(NULL) return (the c-level equivalent of) character() rather than the NA_character_? An empty string and NULL aren't the same. It seems reasonable for Rf_mkChar to give NA_character_ though. ~G On Tue, May 24, 2016 at 8:42 AM, Jeroen Ooms <jeroen.ooms at stat.ucla.edu> wrote: > On Thu, May 12, 2016 at 1:20 PM, Jeroen Ooms <jeroen.ooms at

Dear all, I am sending a patch for extending pdf device to embed popup text and web links. I implemented this feature by using annotation object, a interactive feature of pdf. You can see a sample code for using this feature in the following, and sample pdf is in

Hi, This is such a trivial programming issue, but I can''t find a way to transform, say ''abc'' to ''a-b-c'' without using pattern matching. Any ideas?

Hi, I am happy to announce that I finished the translation of almost all LGPL'ed R headerfiles to Delphi. As a test I did several demos which basically contain delphized versions of all the examples of chapter 5 in "Writing R Extensions". Please have a look in the attachments for details (DemosAndHeaders.txt), more information (Readme.txt) and an example of how it looks

I now have the acts_as_commentable plugin up on RubyForge. This plugin will allow you to add comments to any active_record object in your Rails application. So far the directions are simple, and there are only a few features: To install: ruby script/plugin install svn://rubyforge.org//var/svn/commentable/acts_as_commentable In the readme there is a sample migration you will need to use, with

I've rolled up R-2.6.0.tar.gz a short while ago. This is a development release which contains a number of new features. In particular, the handling of data with a large number of identical strings should be more memory-efficient. Also, a number of mostly minor bugs have been fixed. See the full list of changes below. You can get it (later today) from
