Hi all, I am looking to extend the regression and data analysis capabilities of R through Symbolic Regression that can potentially find implicit equation relationships in the input data. You can find my project proposal at: http://rwiki.sciviews.org/doku.php?id=developers:projects:gsoc2010:syrfr I am looking for a mentor to guide me through the summer on the project under the Google Summer Of

Hi, I need some help to get some of the object orientation, specifically the methods that overload the basic arithmetic operations, from sample C++ code to R. I don't have experience with such advanced language features inside of R. So I was wondering if some of you could help me out in this regard. I have written a simple demonstration of a forward mode automatic differentiator in C++ and

I am reading into Java dput output for a matrix, more specifically for a file backed big-matrix. I basically need to lift dimnames for a matrix from dput output. It's no big deal, but the code is very 'hackish' due to the need to get rid of quotes, endlines, parenthesis, etc. I was wondering if i could manipulate to an extent dput output with some options that define it, for example,

Dear list, I am writing C code to interface with R, and I would like to know the level of mutability for the type of a SEXP. I see that there is a macro/function TYPEOF(), and that it can be used as an l-value, as well as a macro/function SET_TYPEOF(). My question is "should the type be considered immutable, or it can it change after the SEXP has been created and used for a while ?".

This rule does not seem to be widely followed by Clang today. Looking at Parser and Sema, many getters (0 argument functions with names matching /^get[A-Z]/) return mutable references to long-lived objects. Looking through Decl.h, things are a little different: we rarely return references, but do frequently return pointers that provide mutable access to contained objects. On Tue, Mar 4, 2014 at

Hello, I would like for my C function to be able to manipulate some values stored in an R data frame. To achieve this, a need the (real) memory address where the R data frame stores its data (hopefully in a contiguous way). Then, from R, I call the C function and passing this memory address as a parameter. The question: how can we get the memory address of the R data frame? Thank you! L.

Dear colleagues, i am carrying out an ordinal regression model. I try it on SPSS but I "flirt" with R as well. I have a few questions. 1. What is the most reliable/tested/trusted package for ordinal regression in the R world? 2. Also, I have a statistical question. What is the danger of having to many 'empty cells' in ordinal regression? How many empty cells are too many? Do

It seems that the contents of Constant{Array,Struct,etc} are immutable after construction. The only available accessor function is getValues(), which returns a constant reference to a vector of uses. I have the following situation. I am building global (static) array of structs. Hence, I build a vector of ConstantStruct pointers to give to the ConstantArray constructor, etc. However, I have

I have set up Samba so that all users on my small network can read from my one of my Linux shares as well as write to that share. However, when user A saves a file to that share, user B can't open it -- and vice versa. How can I set up samba so that all files written to that share can be read, modified, and deleted by all users? Thanks in advance for an answer to this question.

I suggest adding a 'pivot' argument to qr.R, to obtain columns in the same order as the original x, so that a <- qr(x) qr.Q(a) %*% qr.R(a, pivot=TRUE) returns x. -------------------------------------------------- # File src/library/base/R/qr.R qr.R <- function(qr, complete = FALSE, pivot = FALSE) { # Args: # qr: a QR decomposition, produced by qr() # complete:

Hello. I am new libvirt user. I downloaded and compile the source code with default configuration. I had a lot of trouble before finally found out that python bindings is now a separated package. However the web site still states that python binding is directly supported, and that install extra binding package when libvirt is installed as a binary package. Please consider updating this
