Some formula methods for S3 generic functions use the idiom returnValue$call <- sys.call(sys.parent()) to show how to recreate the returned object or to use as a label on a plot. It is often followed by returnValue$call[[1]] <- quote(myName) E.g., I see it in packages "latticeExtra" and "leaps", and I suspect it used in "lattice" as well. This idiom

Hello All, A simple question. I get some return from the R in my C++ program (via Rcpp package). The result come, as SEXP and it should be a simple numeric variable. How to convert it to double? The code, what i use: stringstream ss; ss << "p <- predict(fit_ar11, n.ahead = 2, doplot=FALSE);" << "p$pred[1]"; SEXP ans; int iRet =

Dear Sir/Madam, I am new in R.I have data corresponding to every day. Problem is that there are some gap i.e. observation couldn't be done on some particular day. I want to place this data frame like exact data frame (every year it will change, Feb 28 or feb29) Maybe I need to make one coulmn of date (for each year, say this dataframe 'frame1'), then I need to place data set on

Dear All, I would like to use - plot, - curve inside a C++ program. What R package do you recommend? Rcpp? Thanks in advance, Paul

Hi, What is the difference between the R installation from source and the R installation from ubuntu repositories. Specifically when I install R-3.1.1 on ubuntu 14.04 from sources ldflags and CXXFLAGS are different that those from the installation from a repo. Installation from sources: R CMD config --ldflags -Wl,--export-dynamic -fopenmp -L/home/prana/prana_R/third-party/install/lib/R/lib

Hi I'm trying to implement something similar to the following R snippet using C.

Hi, I am somewhat new to R and RSPerl, but I think this particular problem has to do with RSPerl and so I am not sure if this is the right forum to ask for help. Nevertheless I am quite sure that many of you would have used RSPerl with R. My hardware platform is a Sun/Solaris V440 server running Solaris 9 operating system I use the gcc-3.4.0 compiler to compile R without any problems. My

Hi, I'd like to construct an R list object in C++, fill it with relevant data, and pass it to an R function which will return a different list object back. I have browsed through all the R manuals, and examples under tests/Embedding, but can't figure out the correct way. Below is my code snippet: #include <Rinternals.h> // Rf_initEmbeddedR and other setups already performed

Hi, I'm wanting to call R from Perl via the RSPerl package. However I cannot seem to install it on my Macbook (OS X Tiger - R 2.6 - Perl 5.8.6). I try to install the source downloaded from the sigmahat website - but it seems to fail - when I search my system for R.pm - I can't find it? Something looks to be going wrong with the make bits?

Hi, I am trying to implement agent groups where agents in a group answer calls from a particular queue. If no agent is available from a group, the calls are directed to agent(s) in another group. Without groups, the calls are added to the queue and agents are called. However, when I introduce the 'group' concept, it seems like the queue application is not called. The calls are never

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. Regards, Spiral [[alternative HTML

This would be easier if base::set.seed() accepted a value of .Random.seed instead of just a scalar integer or, new to R-3.0.0, NULL. If set.seed() returned the previous value of .Random.seed (NULL if there was no previous value) things might be even easier. People should not have to know where .Random.seed is stored. S+'s set.seed() accepts a value of .Random.seed but does not return the

Dear R devel, I have a C++ app that calls into embedded R to perform some analytic calculations. When my app encounters a segmentation fault, R always prints the following crash prompt and asks me to enter an action: *** caught segfault *** address 0x8, cause 'memory not mapped' Possible actions: 1: abort (with core dump, if enabled) 2: normal R exit 3: exit R without saving workspace

Hi, this is continuation for the MMIO accessor rewrite and cleanup. I am currently running nv28 with these patches applied, but I cannot test on PPC. Please, review and comment. If the direction is good, I'll do the same to INSTANCE_{RD,WR} as I did for nv_{rd,wr}32, and change PRAMIN from drm_local_map to simple ioremap. Can the same be done for channel specific mappings, that is
