Dear All, Consider the following trivial code snippet rm(list=ls()) name_vec <- c("color1", "color2") pdf("test_color.pdf") plot(seq(5), seq(5), main=paste(name_vec[1]," and ",name_vec[2], sep="")) dev.off() What I would like to achieve is rather simple to explain, but it is giving me a headache: how can I have two colors in main? Let us

Hi, I was trying to generate RcppDatetime from a string. The main problem for me is that my string contains millisecond. I saw that RcppDatetime takes in double of seconds since epoch. I try to generate a double using boost but has no success. I'm wondering if you have any sample snippet? The string looks like: "2010-03-18 15:50:51.232" Secondly, what time zone RcppDatetime is

Hi the list, In a package P1, I write a function f1 in C, potentially an internal function (not to be called from R). In a package P2, I write a function f2 in C. The f2 function needs to use f1 from P1. Is it possible ? --- 8< ---- In file P1.c --------- double f1(x,y){ .... } --- 8< ---- In file P2.c --------- void f2(x,y,z){ double result; .... result = f1(x,y); .... }

R-exts.pdf discribes S3method a little bit. But I want to understand more on how it is called, implemented and when to use it. I don't find it in an R session. But I see S3method() in some NAMESPACE files. > S3method Error: object 'S3method' not found > ?S3method No documentation for 'S3method' in specified packages and libraries: you could try '??S3method' I

Hi all, I am not familiar with writing R extensions. In a C program, I want to create a SEXP and access it in embedded R. How to let the embedded engine know there's a new vector? For example, after creating a SEXP, parsing 'ls()' in embedded R and then evaluating, STRSXP returned will contain the name of the SEXP. Any help would be appreciated.

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, Can anyone tell me how to embed R code in a C++ file. I am actually using a mac running on the OSX 10.6.2 and the IDE Xcode Version 3.2 and I would like to embed the basic function like geometric, binomial, normal and hyper geometric distributions in a sample cpp file. I heard about the library RInside and i have downloaded the source code for mac but i do not know how to build it in

Hi, Im not sure if this is the right place to post this. I am using Xubuntu Karmic Koala and am trying to use the Rcpp package. I am testing it using a simple code that takes in a vector and adds 1 to each element: #include <Rcpp.h> // This file takes in a vector and adds one to each entry RcppExport SEXP addone(SEXP vec){ // create a local copy of vec Rcpp::NumericVector

Hello, I discovered R two years ago and thanks to the R-community I managed to write some scripts to analyze my data stored in mysql databases. The only problem is that I am the only one using R in the lab. Colleagues mainly use Matlab (but not with mysql, only with text files) but regularly come to me to get data treated with R-scripts !!!. To allow the use of my scripts by other people, my
