I wonder if you might be able to make use of R's "active bindings."
These enable you to set things up so that a user definable function is
called when an assignment is made or when a value is accessed. It's
sort of like overriding assignment for a particular variable, but you
don't need to me

While it _may_ be possible to make this work in current R (I don't
know if it is) this is a Really Bad Idea as it will affect every other
piece of R code run on the system. It also may not work at all in
future versions of R (assignment is sufficiently core functionality
that it may not be impleme

hi everyone,
Im implementing a new RBlas dll but just for optimising sake i need to know
how and WHERE (which source code) RBlas gets loaded. there is a call to
loadlibrary() in dynload.c BUT it seems this is not the function that is
loading Rblas.
how do i know this? well i added the code :(ju
In response to the Aug 20 posting by Vadim, I had the same issue with
all kinds of complaints about row.names when it was not given in the
read.table command; when it was set to NULL (data were actually
shifted to the wrong names). I believe the problem was no comma (or
specified delimiter) at

R has the notion of an external pointer, which is a pointer to C-level
data. Is that what you mean? See ?"externalptr-class" and the 'Writing
