Hi all,
I have been playing with Rcpp, and gotten the Rcpp installed
just fine.
However, when I set up the default "example" package with
Rcpp.package.skeleton(), e.g.
Rcpp.package.skeleton(name="RcppSkeleton")
...I can't get the package to install via any of the usual
methods. During compilation of the C++ code, it hits a
"file not found" error, I think because RcppSkeleton is not
being produced, or not being placed in the appropriate
directory.
Any help welcome! SessionInfo() and various attempts pasted
below

I get the same error when trying to install from inside
R.app as well.
Presumably I have to change something inside the Makevars
file (?), but as I'm just using the default example package,
it seems like it ought to work out of the box.
But here's the current (default) Makevars file:
############################################################
## Use the R_HOME indirection to support installations of
multiple R version
PKG_LIBS = `$(R_HOME)/bin/Rscript -e "Rcpp:::LdFlags()"`
## As an alternative, one can also add this code in a file
'configure'
##
## PKG_LIBS=`${R_HOME}/bin/Rscript -e "Rcpp:::LdFlags()"`
##
## sed -e "s|@PKG_LIBS@|${PKG_LIBS}|" \
## src/Makevars.in > src/Makevars
##
## which together with the following file 'src/Makevars.in'
##
## PKG_LIBS = @PKG_LIBS@
##
## can be used to create src/Makevars dynamically. This
scheme is more
## powerful and can be expanded to also check for and link
with other
## libraries. It should be complemented by a file 'cleanup'
##
## rm src/Makevars
##
## which removes the autogenerated file src/Makevars.
##
## Of course, autoconf can also be used to write configure

Any help appreciated!

We (I'm working with Jiqiang) were hoping to
let Rcpp do the heavy wrapping here following
the std::vector example in the Rcpp modules doc (last
full example).

We are using traits/policies all over our own code,
but this isn't a compile-time type/behavioral config issue. The
types someone passes us in a call that takes a list
could be anything, and we need to check they're compatible
with what we're expecting and handle the error if they're
not.

This could work. We just don't know what's in an
SEXP or how to get the SEXP from the Rcpp::List entries.
What we (I'm working with Jiqiang) need is to be able to
1. access the value of an Rcpp list entry by name.
2. recover the basic type, integer or floating point
3. recover the dimensions
4. recover the values as a vector
Presumably that's available somewhere in the Rcpp::List
if you can use it to communicate back and forth
losslessly with R.

I completely agree with Dirk's last point -- we only
want to use Rcpp as transport to/from R.
Is there a place to find the API doc somewhere,
like what methods are available on an Rcpp::List?
Otherwise, I can just look at the code. I'm about to
try to look through the source now, so maybe I'll be
able to answer our own question.
