R help - Jul 2022 - byte coding compiling.....

Unlikely

See here:

https://www.r-bloggers.com/2017/08/how-to-make-best-use-of-the-byte-compiler-in-r/

Byte code compilation should be automatic in both cases, as I understand
it. Of course, I could be wrong due to special features of parallel
programming, etc.

A reprex might be helpful here.

Cheers,
Bert

Dear Bert,
                 Thanks for your reply...

So
> cmpfun(mclapply)
should  do the job right?

By the by, how can I give a reprex? Reprex of the code that I am giving to
mclapply (as FUN argument)?

Yours sincerely,
AKSHAY M KULKARNI

                          I am using pbmclapply, the progress bar version of
mclapply, from the parallel package. The point is, pbmclapply is three times
faster than mclapply, and I think the most probable reason would be that
pbmclapply is byte code compiled (I can think of no other reason).

I know the cmpfun function from compiler package. If I do:
> cmpfun(mclapply)
will the job be done? The point is mclapply may look for other functions in the
parallel package. So I have to compile the whole package right? How do you do
that? or in general, how do you byte code compile a whole package?

Thanking you,
Yours sincerely,
AKSHAY M KULKARNI
