r - Looking at internal Methods -

i'd able see function that's used when use str(), i'd modify bit own purposes function.

when type str(), following:

function (object, ...)  usemethod("str") <environment: namespace:utils> 

so tried, getanywhere(str):

2 differing objects matching ‘str’ found in following places   .globalenv   package:utils   namespace:utils use [] view 1 of them 

but there's nothing in documentation syntax should using []

so tried, getanywhere(str)[1]:

function (object, ...)  usemethod("str") <environment: namespace:utils> 

sigh. allright, showmethods(str):

function "str":  <not generic function> 

so, how see construction of output str()? or can i?

you want methods() s3 generic such str():

> methods(str) [1] str.data.frame* str.date*       str.default*    [4] str.dendrogram* str.loglik*     str.posixt*         non-visible functions asterisked 

using getanywhere(str) not helpful because str() visible same result if run str @ prompt. need getanywhere() @ hidden methods listed above:

getanywhere(str.default) 

for example.

shame need know kind of generic function list methods; seems user-friendliness improved if r didn't care kind of method type supplied 1 or other of these functions.
