[Rd] for help on building a R package with several R function and a bunch of c, c++
Hope I can get quick help from here, I have a bunch of c, c++ included main function and makefile. It works well on both UNIX and windows. I tried to build R package which include this C++ program and several other R functions. These R function here are independent of c++ code. I prefer to define one R function to call this c++ program (main function). I know how to build R package with just R function, but I don't know how to handle those c++ c code after I copied those code in ./src, I am reading manual "Writing R Extensions" , but I did n't catch the key point . Do you know any easy way to do it? , Thank you in advance! Alex __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Re: [Rd] for help on building a R package with several R function and a bunch of c, c++
I think the first question should be how to build a R function to call a bunch of C ,C++ which include one main program, and a makefile. My goal to build a R package will be next step. I read Rcpp , I am not sure if RcppResultSet can solve my problem or other function. Once I make sure it work I need ask UNIX adminstrator to install it. I think it shouldn't be very complex, as I know to build a R function easy with one C function. Thanks you for yout attention!

Thank you for your help. So far what I did on my notebook as follows. My OS
is windows7.
Â
I downloaded Rcpp windows version, and load library("Rcpp") then.
Â
1, Change main funnction to f1.cpp, remove makefile.
2 ,run Rcpp.package.skeleton(name="test",list=c("rec1.R","rect2.R"))
3, edit  /man, /R, copied my exist file whch I have done sucessfullyÂ
without any c++ program before.
4, copy f1.cpp and all other related cpp and c into /src/
5. Rcmd build --binary test
Â
It showed--
Â
making DLL

I checked the path, it did have C:\Users\alex

Â
I don't know how I can fix the problem. do you think it could be problem there

You should jump straight to making a package. You are making you life
difficult with this "main program & makefile" model.
Install Rcpp and try to use the Rcpp.package.skeleton, this will create
a simple package that uses some C++ classes from Rcpp, as well as an R
function that calls them.

We don't know what your problem is. We can answer a question, but we
cannot guess the question for you.
Rcpp works, please refer to our unit tests, for example look at this

Re: [Rd] for help on building a R package with several R function and a bunch of c, c++
Hi,
Yes, the problem is with spaces in path names. This has been fixed and
will appear as Rcpp 0.7.8 in a few days.
If you are in a rush, you can build it from svn, or quote the path that
is returned from CxxFlags.
Feel free to get back to us with more questions, although I'd encourage
you to use the dedicated Rcpp-devel mailing list :
https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel

Re: [Rd] for help on building a R package with several R function and a bunch of c, c++
I built R package with only R code before, this is first time I build R package
with mixed R code and C, C++ code. I would try Rcpp on our center UNIX, before
I ask the administrator to install it, I need confirm several issue are right.
Thank you for you patient.
1, I change main function as a general function with certain name such as void
tranptest(char* filename[], double* para[]), and copy this file and other
related c, c++ h, program to /src, and removed makefile.
2, I noticed there is Makevars after I ran Rcpp.package.skeleton,
do I need modify this file before I run R CMD build? what I need do for
rcpp_hello_world.cpp rcpp_hello_world.cpp? it is template file handled by the
program or it is for me to edit it as template?
3, Do I need write a R function such as tranptest<-function(inputfile,
ctlfile,outfile, param1,param2,param3)
{
filenames<-c(inputfile,ctlfile,outfile)
params<-as.vector(c(param1, param2,param3))
.C("tranptest", as.character(filenames),as.double(params))
}
before I run R CMD build? if so, that means I put this R function in /R?
4, Do I need do anything to run library.dyname to load those complied objects?
Where I can make sure it successful and I can use .C("tranptest",) in R
before the wholepackage installed?
Thank you so much!

Thank you for you patient.
1, I change main function as a general function with certain name such as void
tranptest(char* filename[], double* para[]), and copy this file and other
related c, c++ h, program to /src, and removed makefile.
I'd encourage you to use the .Call interface,
2, I noticed there is Makevars after I ran Rcpp.package.skeleton,
do I need modify this file before I run R CMD build?
no
what I need do for rcpp_hello_world.cpp rcpp_hello_world.cpp? it is
template file handled by the program or it is for me to edit it as template?
those are examples that we expand to show the kind of code you can
write. feel free to dump them.
In particular, it shows you how you declare c++ functions to be used by R:
- The RcppExport prevents c++ mangling. see the rationale for this in
writing R extensions. (RcppExport is just an alias for extern "C")
- The function returns a SEXP (see writing R extensions)
- The function takes zero or more SEXP as input (see writing R extensions)
So I'd suggest you write your function something like this :
RcppExport SEXP tranptest( SEXP filename_, SEXP para_){
Rcpp::CharacterVector filename( filename_ ) ;
Rcpp::NumericVector para(para_) ;
// use filename and para to do whatever you want to do with them
// return something
}
3, Do I need write a R function such as tranptest<-function(inputfile,
ctlfile,outfile, param1,param2,param3)
{
filenames<-c(inputfile,ctlfile,outfile)
params<-as.vector(c(param1, param2,param3))
.C("tranptest", as.character(filenames),as.double(params))
}
before I run R CMD build? if so, that means I put this R function in /R?
Again, I suggest you look into the .Call interface and go for something
like this:
.Call( "tranptest", filenames, params, PACKAGE = "yourpackage" )
4, Do I need do anything to run library.dyname to load those complied objects? Where I
can make sure it successful and I can use .C("tranptest",) in R before the
wholepackage installed?
Rcpp.package.skeleton adds a useDynLib directive to the NAMESPACE so you
should be fine.
Thank you so much!

Alex, Can you _please_ stop spamming r-devel? Romain and I repeatedly pointed the existence of the rcpp-devel list out to you. Please consider using it. There are existing packages that use what you want to try use. I find it beneficial to start from a _working example_. Take e.g. the earthmovedist package on R-Forge, try to understand how it works and how it makes use of Rcpp and adapt your use case to what works. If it fails, send pointed messages with repeatable examples and clear error message to an appropriate list, eg rcpp-devel.

Yes, that's perfect - for the kind of usage you don't need Rcpp at all
- R supports C++ sources out of the box. Just make sure your tranptest
function is either in a .c file or you put
extern "C"
in front of it if it's in .cpp , e.g:
foo.cpp:
extern "C" void tranptest(char **fn, double *par) {
...
}
2, I noticed there is Makevars after I ran Rcpp.package.skeleton,

.C("tranptest", as.character(filenames),as.double(params))
}
before I run R CMD build? if so, that means I put this R function
in /R?
yes, in R/foo.R (replace "foo" by any name you want)
4, Do I need do anything to run library.dyname to load those
complied objects?
If you have a namespace just add
useDynLib(foo)
where "foo" is the name of your package. If you don't have a namespace
(or don't kwno what that is ;)) just add a file R/zzz.R with the
following content to your package:
.First.lib <- function(libname, pkgname) library.dynam("foo", pkgname,
libname)
where "foo" is the name of your package.
Where I can make sure it successful and I can
use .C("tranptest",) in R before the wholepackage installed?
It's really simple - you don't need to install the package to test it.
Assuming "foo" is the name of your package:
Build the sources:
R CMD SHLIB -o foo.so *.c*
start R in the same directory:
R
# load the library you just compiled
dyn.load("foo.so")
# test your code
.C("tranptest", c("file1", "file2"), as.double(1,2,3,4))

Dirk, he was not asking about Rcpp originally - he was asking about C++. He seems to be reluctant to use Rcpp due to the complexities involved (for which I don't blame him) so going back to simple C++ basics of R- ext (which is what he was using in his example) is really R-devel topic I think ...

Yes! that is what I am looking for. When I post my question, I said I cannot
catch the key point in "Writing R Extensions".
Follow your suggestion, I almost have reached my goal although I passed the R
CMD check mypackage. Before I install it (I need ask UNIX adminstrator to do
it), I check the package, I got the information

*** caught segfault ***
address 0, cause 'memory not mapped'
Traceback:

Do you have any clue about the error? I think it is very close tothe end.

I don't see your C code so I can't tell -- use "R -d gdb" to run R in
a debugger so you can look at the exact spot of the crash. Is it
possible that you get thrown off by the 0-based indexing in C and
opposed to 1-based indexing in R?
in
extern "C" void tranptest(char **fn, double *par) {
you want to access the values as fn[0], fn[1], fn[2] and par[0],
par[1], par[2], .. etc.
