Hi all, I often have to peek at large data. While head and tail are convenient, at times I'd like some more comprehensive. I guess I debug better in a more visual way? I was wondering if there's a way to override the default data editor. I could of course dump to a txt file, and look at it with an editor/spreadsheet, but after doing it a few times, it gets boring. Maybe it's time for

Hi, This is a simple trick to get autoclose parenthesis on windows. If you like how StatET autocloses parens, but like to use the lighter Vanilla R, you can use autohotkey (http://autohotkey.net) to provide this functionality. Simply put the below code in a text file, rename extension as .ahk and doubleclick on it to execute. ------------------ code starts here 8< ------------------ ;

Hi, I'm trying to get Rmysql to work o windows server 2008 64-bit. I have the latest build of mysql installed (mysql-5.1.34-winx64). When trying to load Rmysql, I got a warning that Rmysql is linking to an old-ish mysql build (5.0.67). I could do some basic stuff (the connection works) but it breaks when trying to read a large table. So I set up to use the buld 5.0.67 that Rmysql likes. 10

Hi, I've realized that the scrolling behavior in View() is unlike most other applications. It seems that the minimum scroll size is very large for large objects( i.e., a vector of 1M integers), and it might be that this scroll is proportional to the size of the object. Try this: a = 1:1000000 View(a) Click once on the scroll arrow down. It will move to item 1001. It could be that the scroll

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm doing some basic operations on large sparse matrices, for example getting a row. it takes close to 30 seconds on a 3Ghz machine, and shots the memory usage up to the sky. I suspect there are dense intermediary steps (which, if true would defeat the purpose of trying to use sparse representaitons). As much as I try understanding the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have something strange here... I want to subset a large sparse matrix, with the subset being still in sparse form.

Hi, I'm trying to install R with atlas in ubuntu karmic 64. I do a lot of matrix operations so I need performance. Doing grep sse2 /proc/cpuinfo tells me tha my CPU supports SSE2. But I don't see libatlas3gf-sse2 in the package repositories. Also, there seem to be some gotchas on how to install atlas, even the vanilla one, as described here:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, A follow up to my previous post. It'd be good to have syntax highlighting in the html help pages. There is highlight (http://www.andre-simon.de/) which seems to be open source. Since code is delimited in the help file format, it should not be too difficult to run a highlighting program (actually, vim and emacs do this too) recursively and

Hi, Chm (compiled help) is a microsoft invention. It's the default help system under windows, but not so under linux. I found that (at times) I like better how chm help looks. Since there are chm viewers under linux, using chm help files should be possible. Has anybody tried to set R so it opens chm by default? I'm sure there's some flag or Rprofile var that could get this done.

Dear R users, People who uses vim in Linux/Unix may be interested in checking the plugin for R that I'm developing: http://www.vim.org/scripts/script.php?script_id=2628 The plugin includes omni completion for R objects, code indentation and communication with R running in a terminal emulator (xterm or gnome-terminal). This last feature was already present in Johannes Ranke's plugin.

Hi, I wonder what kind of interest there is on Test Driven Development (TDD) in R. Test Driven Development consists of writing the test before the function, and iteratively build the function until it passes the test. Python and Ruby (specially Ruby) have very strong test-oriented cultures. In fact, in Ruby at least the custom is to do TDD and lately Behavior-driven development (BDD). In BDD,

Hi all, I am using ISOdatetime, and I just found out that when I do ISOdatetime(1995,03,26,2,10,0) (or any other value under minutes or seconds) I get NA This does not happen with the same time in other dates, nor with different hours in the same date.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, There are many sites to get bite-sized chuncks of code. The nice thing is that they use syntax highlighting. Examples: http://dpaste.com/ http://pastie.org/ http://pastebin.com/ Twitter with a link to a syntax highlighting site would do wonders. There are plugins for most (good) editors to post directly to the site from the editor.

Dear all, I'm starting to learn R, but I'm already programing for a while, using ViM as editor. Therefore I'd like to be able to use R together with ViM. My question now is, whether there are already people out there knowing how to do this in a similar easy way as with Emacs, and if those would be willing to share this knowledge. I did already research on the web on this topic,

Hi, I'm attending summer School at UCLA (IPAM) on "probabilistics models of cognition". I have been an R-user since v. 1.4.1, but was trained in the frequentist tradition (as most psychologists!). I found that all faculty here use matlab and Murphy's bayes net toolbox. I have not had the need to use matlab before, and would love to stick to R for graphics models and

At the suggestion of many people, I have installed emacs on my linux (Fedora 8.0) computer with the intention of using emacs as window interface to R (2.6.0). I have gone though the emacs tutorial and don't see any information about how I should use emacs to run R. Can anyone suggest a document that I might read? In the past I have used R on a Windows XP system and used the built-in windowing

Hi All, I recently found gmane http://gmane.org/ It's a system to covert mail to news and back, with the nice property of keeping a searchable archive... Very convenient if you are subscribed to many lists and don't want to have your mail box cluttered. I use it to read several mailing lists already, but R is not available there. I wonder if the admins know about gmane and if they

Hi, I am new to R and I need to perform multiple chi-square tests. I manage to perform one at a time, but is there a specific command to do multiple tests?
