[R] byte coding compiling.....

[akshay kulkarni]

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

Unlikely

See here:

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 members,
                          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,
