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< ------------------ ;

-----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, 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

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

-----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

Hi, While I'm a devoted vim user, I'm testing ESS :) How do I set the working directory when using ESS and R under windows? When I try to launch R, it asks for a directory. In windows, it simply doesn't let you pick a directory on the 'open' dialog. It may be a problem with windows server 2008 64 bit, though, as it seems really basic. Thanks. Best, -Jose -- Jose Quesada,

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,

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 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 need to multiply all columns in a matrix so something like apply(x,2,sum), but using multiplication should do. I have tried apply(x,2,"*") I know this must be trivial, but I get: Error in FUN(newX[, i], ...) : invalid unary operator The help for apply states that unary operators must be quoted. I tried single quotes too, with the same results. Thanks, -Jose -- Jose

I'm a Windows (non C++) software developer and I'm wanting my software to run under Wine as best as possible. My app uses CHM help files which are displayed in Windows when pressing F1 or clicking Help on the menu, but it does not work under Wine on Linux. It does absolutely nothing. Is see there are CHM viewers available but Wine does not seem to use them. Any suggestions? Thanks,

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The Center for Adaptive Behavior and cognition (ABC) at Max Planck Institute, Berlin (Germany) is looking for Student research assistants.

Hi, I'm trying to use a similarity matrix (triangular) as input for pam() or fanny() clustering algorithms. The problem is that this algorithms can only accept a dissimilarity matrix, normally generated by daisy(). However, daisy only accept 'data matrix or dataframe. Dissimilarities will be computed between the rows of x'. Is there any way to say to that your data are already a

Hi, Has anyone run any R vs Python (numpy) tests? I'd love to see what the differences performance-wise are, specially handling large sparse matrices. Since both rely on external C code, there might not be much of a difference. If you know and use both languages, what are the main differences and what made you stick to one over another? I also noticed that there are strong libraries

-----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. Easily achievable with mm[i,,drop=F] , right? Well, it doesn't work on the matrix I'm working on. This is a very large wikipedia Matrix (now I can play with it as I just got 16Gb of memory): > mm at Dim [1] 793251

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:

Dear R users, I need to normalize a bunch of row vectors. At a certain point I need to divide a matrix by a vector of norms. I find that the behavior of Matrix objects differs from normal matrix objects. Example the following code examples differ only in xnormed changing from normal to Matrix object: x = matrix(1:12,3,4) x = as(x, "CsparseMatrix") xnorms = sqrt(colSums(x^2))

(Extremely sorry, disregard previous email as I hit send before pasting the latest version of the example; this one is smaller too) Dear R users, I want to apply a function that takes two vectors as input to all pairs (combinations (nrow(X), 2))of matrix rows in a matrix. I know that ideally, one should avoid loops in R, but after reading the docs for do.call, apply, etc, I still don't know
