...compatible with GPL, by making the relevant header files available under the LGPL. This was an explicit change that was made in February 2001, and allows for DLLs that require the API header files for compilation and are linked against R.dll to not be "infected" with the GPL. However the Rembedded.h header file isn't included in the list in the doc\COPYRIGHTS file, and the copyright statement in the Rembedded.h header file lists the GPL and not the LGPL as the relevant license. So it doesn't look like it is allowed that I be able to use the R invocation API to launch R and embed it...

...hrough the example in the help page on calling the .dll directly ( http://cran.r-project.org/doc/manuals/R-exts.html#Calling-R_002edll-directly ). When I compile I consistently get the error that getDLLVersion() as well as get_R_HOME() and getRUser() are undefined references. These are defined in Rembedded.h ln60 as: extern char *getDLLVersion(void), *getRUser(void), *get_R_HOME(void); I included Rembedded.h from the example. I searched the entire R directory for the string getDLLVersion and only found it in Rembedded.h and the help documentation (for the .dll directly example). Am I missing some...

...from the web, ran the "Embedded" tests, and grep'ed / looked at the source code. It is now my understanding that there are several ways I could use R from C: 1. Pass data from C to an R function, loaded during R runtime; 2. Build R statements and use Rparse.h to execute them; 3. Use Rembedded.h to call R's C functions; 4. Directly call R's C functions. 4) would be the fastest (I think?), and speed is some concern. However, I am finding it very tough going to discover how to implement this. For example: given two matrices represented as arrays of doubles and their numbers of row...

...ions about the direction to give to a user, knowing his/her habits. Because I used R back at school, I thought I can use some of his functions in my application, as a shared library. I reviewed the "Rinternals" and "R extensions" documents, and decided to give a try to the REmbedded.c file. Compilation and linking went well. But the execution failed with a "Fatal error: R home directory is not defined". Does it mean that R has to to be distributed with my application or, did I miss something in my readings ? If that is of any importance, I am working on unix but...

I have a vague idea but still I cannot understand how I would evaluate an R expression like Covariance <- round(cov(100 * SWX.RET), digits = 4) using lang, install and R_tryEval. 2) What exactly does install do? 3) I wrote the following code: #include <Rinternals.h> #include <Rembedded.h> int main (int argc, char** argv) { SEXP e,val; int errorOccurred; Rf_initEmbeddedR(argc, argv); // library("fPortfolio") PROTECT(e = lang2(install("library"), mkString("fPortfolio"))); R_tryEval(e, R_GlobalEnv, NULL); UNPROTECT(1);...

...ot;t.test(x,conf.level=(1-p))$conf.int[2]" I had an idea for an addition to the embedded API. There are a number of hidden or static parse functions (R_ParseBuffer, R_Parse1Buffer, etc.) which take an IoBuffer* and returns a parsed tree. If one or more of these functions were exported to the Rembedded.h API we could do something like the following: R_Expr = R_Parse1Buffer(&R_ConsoleIob, 0, &status); if (PARSE_OK==status) { ... value = eval(R_CurrentExpr, rho); ... } or possibly simplifying the interface to take the CMDL string: R_Expr = R_Parse1Line("t.test(x,...
