I am designing a remote procedure protocol for R, which basically performs a
do.call on data and arguments supplied by a client. However, I am
experiencing unfortunate behavior of the do.call function. The function
do.call seems to serialize all objects in the args list, resulting in an

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

Oliver,
For an example of moving averages, take a look at the C source of the xts and
TTR packages. The sources are browsable on R-forge.
In short, REAL etc are functions to extract the data of an SEXP. They need to
match the types coming in. So your C needs to check the type and branch
