I'm having difficulty with Rprof. I have a documentation example test.qss
that
runs fine without profiling, but under Rprof,
> Rprof()
> source("test.qss")
Error in standardGeneric("model.matrix") :
UseMethod used in an inappropriate fashion
Luke wrote about a similar circumstance last summer:

# This sounds like a bug in the usemethod code. Profiling adds an extra
# evaluation context around builtins and that can confuse things that
# don't take this into account. I unfortunately don't have time to
# track this properly now, but on a quick glance it looks like changing
cptr = R_GlobalContext;
if ( !(cptr->callflag & CTXT_FUNCTION) || cptr->cloenv != env)
error("UseMethod used in an inappropriate fashion");
#
# it two places in objects.c to
#
cptr = R_GlobalContext;
if (cptr->callflag == CTXT_BUILTIN)
cptr = cptr->nextcontext;
if ( !(cptr->callflag & CTXT_FUNCTION) || cptr->cloenv != env)
error("UseMethod used in an inappropriate fashion");
#
# might fix this.

I tried this, on my solaris "R version 1.7.0, 2003-02-05" but got
complaints
about the use of env from make. So I quickly retreated. Any thoughts on this?
