[R] How to call time series functions from C ?
Hi everyone, I meet the problem to call R from C. Can someone tell me is it possible to call time series functions(such as ar and arima)from C program on linux platform, and then compile the C program to a standalone executable file? I know we can call some function defined in Rmath.h , but I have not found the entry point for time series function. I would very much appreciate receiving your response ! ^_^ bin, dong goo...@126.com Buaa, Beijing PR China [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

There are none, but you can write a front end for R, and it can evaluate R expressions, etc. The procedure is described in the Writing R Extensions manual. Remember that if you distribute the program you do need to follow the GPL, and distribute all of R as well as all of your own program in source code form.

hi Duncan, tks for you response, it's depressed to know that i can not use time series of R to finish my study.

Re: [R] How to call time series functions from C ?
you have a couple of options. If you require specific R functions to do what you want, then you will need to call R from C. I believe that Dirk has been working on an RInside package that does this. Alternatively, you can use my tslib package, which is a general time series library written in c++. It's public interface in R, is the fts package, which just wraps the c++ library to R functions. sources are available here: http://github.com/armstrtw/tslib/tree/master http://github.com/armstrtw/fts/tree/master If you want to try out tslib, feel free to contact me off list for help. -Whit 2009/5/7 Duncan Murdoch murd...@stats.uwo.ca: On 5/7/2009 10:55 AM, goon83 wrote: hi Duncan, tks for you response, it's depressed to know that i can not use time series of R to finish my study.

Do you have to use the entire xxxGB at once? If not store it in a database and fetch the portions for the current analysis as you need them.
