Profiling: attributing costs to place of invocation (instead of place of evaluation)?
...ply" "sapply" "replicate" "f"
This attributes the cost to the replicate() call to f(), where the call
is actually defined. From my experience, this will give a much better
understanding of the actual costs of each part of the code. The SIGPROF
handler looks at sysparent and cloenv before deciding if an element of
the call stack is to be included in the profile.
Is there interest in integrating a variant of this patch, perhaps with
an optional argument to Rprof()?
Thanks!
Best regards

eval and Calling Frames
...ame
3. `evalq((function() sys.parent(1))())` returns a lower frame number
?? than `evalq(sys.parent(1))`
The root cause of this is that the `evalq` **closure** sets a context,
but then the C-level `do_eval` it invokes sets another one[1] with the
new `evalq` context as the calling frame (`cptr->sysparent`)[2].? This
then interacts with how `sys.parent` resolves parents when a target
frame appears more than once in the context stack.? `sys.parent`
returns the oldest context that matches[3], and in this case `f`'s
frame appears twice because `evalq` adds it via `do_eval`.
One option is to cha...

couldn't find function "print.tframe"
I have an object with an attribute "tframe" for which there is a generic method
print.tframe and also a method print.tframe.default defined in a library.
However, when I use attributes(object) I get the message
$tframe
Error: couldn't find function "print.tframe"
It's as if <primitive: attributes> is not looking through the search list?
Any suggestions?
