Dear R-developers, Using .Call I pass a S4 class with e.g. the following class definition: setClass("mmatrix",representation( data="matrix") ) On the "C side" i do mat = GET_SLOT(vs,install("data")); and then: printf("%f\n",NUMERIC_POINTER(mat)[1]); The above print statement produces the correct output if xx<- new("mmatrix")

Dear R-helpers, The function optim implements algorithms that I would like to use. I have function implemented in R, which given the parameters of which minimization is to take place returns a scalar as well as the gradient. Unfortunately optim requires two function _fn_ and _gr_ where fn returns the function value and gr the gradient. Splitting my function in two functions would be easy,

I''m developing a system similar to the ForumExample (http:// wiki.rubyonrails.org/rails/pages/ForumExample), and stumbled upon the following. Let''s say I wanted to get all the categories a certain user posted in.

Hi there! I been using samba3 with ldap for years, and now im about to move to samba4 to leave the slapd. I didnt try yet to migrate the directory from samba3 to samba4. But i did setup a new domain and everything looks ok. My doubt is related to the configuration of the computers with linux so that they can take advantage of the users and passwords of ldap. But also, groups that are unix

I have Asterisk 1.0.5-BRIstuffed-0.2.0-RC5 up and running. Everything seems to be running fine but after some time asterisk just goes crazy (even withouth any incoming or outgoing call activity perviously).

"docusers" is the UNIX home directory for document users. their individual home dir is created under their user id. so, Paul 's home directory structure is : /docusers/paul Below is an extract from the

Dear R-developers, I am working on an C interface to some c functions. I compiled the c file using R CMD SHLIB without any compilation errors. All libs used are added to the LD_LIBRARY_PATH. However dyn.load("interface.so") produces undefined symbol: N_VNew_Serial; which is defined in one of the libs I link against. Where, and how to start searching for the error? Eryk

Dear R-users, I have the following data x <- runif(300,min=1,max=230) y <- x*0.005 + 0.2 y <- y+rnorm(100,mean=0,sd=0.1) y <- y%%1 # <------- modulo operation plot(x,y) and would like to recapture the slope (0.005) and intercept(0.2). I wonder if there are any clever algorithms to do this. I was looking at the function lm.cirucalar. Is this the method to use? If, which of the

I used this approach and it worked find until I hit, what I believe is, a bug in the register coalescer. When the register

I'm curious if there are users of RPy on this list. I've recently created a gui front end using Tkinter for some python scripts I've written for some of our internal operations and I am quite pleased with how this program works. I wonder if it is possible to also get this gui to run R functions through the use of RPy. Going even a step further, I wonder if it is possible to get this

Hi, I use llvm-lit in my own project. Works fine so far. However, executing the tests, I get output directories which are empty. Whats the role of them? I could not find any hint in the docu. I was expecting that e.g. for RUN: X, the output of X would be located there. I can use RUN: X > log, then I get a log file right besides the test file, and not in oputput. Where can I find more docu

Hi! I encountered some things trying to build own packages under Windows 2000 for which i found no answer in the documentation. First. 1. I do not found the rcmd.exe in the bin directory of R_HOME. I installed R using the setup.exe 2. I updated the R intatllation with one of the zip files. (rw1041sp.zip) now i had the rcmd.exe in the bin. 3. I do not found any hint in the docu that perl is

Hi all - I've been working on a lite ORM and database abstraction package for R. Formatting complex queries by hand has always been an error-prone hassle, so I've tried to do away with that as much as possible, instead, using R objects to represent elements of a database system (statements, clauses, operators, functions, fields, tables, etc.). R5 classes have made the development of this
