Hello
We have a C++ class with several methods that manipulate an object. How is it
possible to create several instances of that class *from R* in the C++ realm,
which can then be accessed via a given name character? Symbolic example (we
hope this illustrates our problem):
// C++ side:
class F
Hello
Thanks again for help!
We have attached version info, code, and contents of 00install.out at the end
of the message. The package can be found here:
http://sovo.md-hh.com/files/Foo.tar.gz
We had followed Dirks explanation in the Rcpp modules vignette and the
presentation of Rcpp modules.

Hello, an S4 class "Foo" is defined with a setter, $. For several reasons, the
setter calls a function, .foo.update(). However, bypassing the argument names
of the setter does not work. Question 1: Why not and how can I fix this?
Question 2: What is the way to define either the function or the s
Hello
Apologies for cross-posting, the discussion should (if) go to R-devel, but I
also want to reach the rcpp-devel people.
My C++ class FOO is a module available through Rcpp, and it works fine and is
-- so far -- bug free. With trying to further develop my R package, I thought
it was a good

Hello, I am working with a reference class:
Foo <- setRefClass("Bar",
fields = list( a = "numeric"),
methods = list( baz = function( xa ) a <<- xa )
)
x <- Foo$new()
x$baz(2)
x$a
y <- new("Bar")
y$baz(4)
y$a
But that might be confusing, since new(Foo) does not work and neither does
Bar$new()
Hello
I have a package with a configure script (--include-something). How does the
package pass the check on CRAN, that is, how should I signalise that check and
install may need options?
Thanks

Hello, the compilation of the GUTS package on CRAN for Mac produces the

Thanks Simon, Uwe and David for your helpful answers. English is not my primary
language, so I was hypothesising a bit about the correct interpretation of
"inlining" and "supply inside". I thought it meant copying the headers inside
the package. I was already inspecting RQuantlib but I did, so f

Hello
I tried to define replacement functions for the class "mylist". When I test
them in an active R session, they work -- however, when I put them into a
package, they don't. Why and how to fix?
make_my_list <- function( x, y ) {
return(structure(list(x, y, class="mylist")))
}
mylist
No. I fixed that, the NAMESPACE file now contains:
S3method("[[<-", mylist)
S3method("$<-", mylist)
It still does not work. I also created a print method (print.mylist) which did
work out of the box, regardless of being in the NAMESPACE file or not. Could it
be somehow in here (also in my NAMES
