How to use pmap over a partition-all list of list?
Hi there, I have this: *user=* (partition-all 5 (range 1 20)) ((1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)) And I would like to apply the *pmap* over the partitions, something like: (the line bellow doesn't work) *user=* (pmap + (partition-all 5 (range 1 20))) *I would like to have this (pmap + (1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)) instead of this (pmap + ((1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)))* How can I apply pmap over a partition-all result? If it's possible, by doing that am I distributing the load better than if I used the pmap with the whole list?

Re: How to use pmap over a partition-all list of list?
Use this: (pmap #(reduce + %) (partition-all 5 (range 1 20))) OR as you yourself said you can use 'apply' instead of reduce Jim On 02/02/13 12:31, Leandro Moreira wrote: Hi there, I have this: *user=* (partition-all 5 (range 1 20)) ((1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)) And I would like to apply the *pmap* over the partitions, something like: (the line bellow doesn't work) *user=* (pmap + (partition-all 5 (range 1 20))) /I would like to have this (pmap + (1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)) instead of this (pmap + ((1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)))/ How can I apply pmap over a partition-all result?

Re: How to use pmap over a partition-all list of list?
aaa you want a scalar as the result? then use an outer reduce as well: (reduce + (pmap #(reduce + %) (partition-all 5 (range 1 20 =190 Jim On 02/02/13 13:10, Jim - FooBar(); wrote: Use this: (pmap #(reduce + %) (partition-all 5 (range 1 20))) OR as you yourself said you can use 'apply' instead of reduce Jim On 02/02/13 12:31, Leandro Moreira wrote: Hi there, I have this: *user=* (partition-all 5 (range 1 20)) ((1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)) And I would like to apply the *pmap* over the partitions, something like: (the line bellow doesn't work) *user=* (pmap + (partition-all 5 (range 1 20))) /I would like to have this (pmap + (1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)) instead of this (pmap + ((1 2 3 4 5) (6 7 8 9 10) (11 12 13 14 15) (16 17 18 19)))/ How can I apply pmap over a partition-all result?

Re: How to use pmap over a partition-all list of list?
Hi Jim, Thanks for your help time, how do I apply instead of reduce? I was looking the documentation of pmap and it says *(pmap fn coll colls)* So I think we can use pmap this way: *(pmap + '(1 2 3) '(4 5 6) '(7 8 9) )* Which gives us the result: *(12 15 18)* My intention it's only to *use range and partition to substitute that*, but I think partition-all doesn't work like separated argument as list, instead. When we type: (*partition-all 5 (range 1 20))* Results in this: *((1 2 3 4 5) (6 7 8 9 10) ...* There is any way of *transforming* (maybe a macro or destruct way) this list in *several colls argument as expected by pmap* signature (fn coll colls)?

Re: How to use pmap over a partition-all list of list?
this works: (apply pmap + (partition-all 5 (range 1 20))) And then reducing the overall result: (reduce + (apply pmap + (partition-all 5 (range 1 20 Leonardo Borges www.leonardoborges.com On Sun, Feb 3, 2013 at 12:35 AM, Leandro Moreira leandro.rhc...@gmail.com wrote: Hi Jim, Thanks for your help time, how do I apply instead of reduce?

Re: How to use pmap over a partition-all list of list?
apply does exactly what you're describing...it treats a collection as several arguments: (apply + [1 2 3 4]) is equivalent to: (+ 1 2 3 4) = 10 so (pmap + '(1 2 3) '(4 5 6) '(7 8 9) ) is equivalent to: (apply pmap + ['(1 2 3) '(4 5 6) '(7 8 9)]) no need for macros and stuff...actually apply is a macro... hope that helps Jim On 02/02/13 13:35, Leandro Moreira wrote: Hi Jim, Thanks for your help time, how do I apply instead of reduce?

no need for macros and stuff...actually apply is a macro... Not really, it's a function.
