Hello. I have another rect question. If I want to make a lot of rectangular, without borders, and without any spaces between them, how could I do it? I.e. > plot(-1:1., -1:1., type = "n") > rect(0,-1,1,1,col="red",lwd=0,border=F,xpd=T) > rect(-1,-1,0,1,col="blue",lwd=0,border=F,xpd=T) will produce two rectangular, but there is space between them. How

Hello. I am porting Splus library to R, which use S "graphics.h" and "device.h", the library makes a number of high resolution plots using these. Does anyone have an experience with similar porting? I don't really want to rewrite all C code, so any recommendation would be helpful. Thanks. --------------------------- Vadim Kutsyy vadim at kutsyy.com

My server has 128 GB of RAM. However, R halted ever before it uses the memory. I have been able to load upto 250 CEL files but this time I wanted to test what would happen if I want to normalize 400 chips. Thanks

Is there a quick way to make boxplots groups by two variables? By that I mean, that if x axes have values ("A","B","C"), than at each value there would be a few boxplots each for a value of second variable (say ("1","2","3")).

Hello, Does anyone know a way to connect from R on Linux box to TeraData server? I can use ODBC connection on Windows box, but with amount of data I need (and prefer) to use large Linux box. Thanks, Vadim

I'm using R 1.8.1 (Win32, Linux) and have some difficulties using validation functions for S4 classes. The problem is if I specify a validation function with setValidity("myclass", validate.myclass) object validation is only performed when I create an instance using new("myclass"), or when I explicitly call validObject(x) where x is of class "myclass", of

Hi, I am trying to put some graphics I have generated from R on a webpage using dev2bitmap to create a bitmap, .BMP, file. When I look at my notes from 2 or 3 months ago I was successfully able to put the ACTIVE device plot result into a bitmap file using a command such as: dev2bitmap("InsectSpray.BMP") Job done! Now when I try the same command, I get the following: >

Hi, Encouraged by a tip from Simon Urbanek I tried to use the S3 machinery to write a faster version of the data.frame class. This quickly hits a snag: the "[.default"(x, i) for some reason cares about the dimensionality of x. In the end there is a full transcript of my R session. It includes the motivation for writing the class and the problems I have encountered. As a result I see

Many thanks to Nick Ellis, Vadim Kutsyy, Charles Berry, and Bill Dunlap for providing thoughts and alternative solutions to the problem. I have included Nick and Charles' notes in full below and a summary of the others. Thanks also to Bill for telling me about an inconsistency in how the first argument of sample is interpreted. I had ignored this, resulting in a major bug. Each person

Hello, JIT compiler interferes with internal R completions: compiler::enableJIT(2) utils:::functionArgs("density", '') gives: utils:::functionArgs("density", '') Note: no visible global function definition for 'bw.nrd0' Note: no visible global function definition for 'bw.nrd' Note: no visible global function definition for 'bw.ucv'

Hi, In the code below, MyNamespace::MyClass_ptr will be named "struct.boost::MyClass_ptr" by llvm-g++, and not "struct.MyNamespace::MyClass_ptr" as I expected. I observed this with the real boost::shared_ptr but used the code below (also attached as structnametest1.cc) on the demo page (http://llvm.org/demo/index.cgi) to reproduce the behavior. When I extended my test code

I initially sent this to the biocore mailing list - but it was suggested that r-devel would also find it interesting. Many of us use a macro like #define CALL_DEF(fname, nargs) { #fname, (DL_FUNC)&fname, nargs} for use in function registration for use with .Call. For example, using the example from R Extension manual, if we want to register a C function myCall with three arguments, we

Hello everyone, I'm working on a package using S4 classes and methods and I ran into the following "problem" when I tried to create an "apply" method for objects of one of my new classes. I've found a way around the problem but I wonder if I did not paint myself into the corner. I'd like your opinion about that. So I have an object "myObj" of class

(Sorry for the cross-post--- I wasn't sure which list is more appropriate...) Hi everyone, I've run into segfaults when using my randomForest package on large dataset (e.g., 100 x 15200) and large number of trees (e.g., ntree=7000 and mtry=3000). I'm wondering if anyone can give me some hints on where to look for the problem. The randomForest package mainly consists of two things:
