R help - Aug 2021 - coercion to an object...

dear Enrico,
                       it works. Thanks a lot. I spent over an hour looking for
this function in the web, but was bootless. Do you have any way to get functions
where you are given what it has to do? The most common case is that you are
given a list of functions, but they number to over 100000. Any idea to find them
without resorting to help from another R expert?

yours sincerely
AKSHAY M KULKARNI

you convert this character object to the object A. i.e I want a function f such
that class(f("A")) = class(A) (of course, class("A") =
"character") . f should just coerce the character to the object
represented by it.

Perhaps ?get is what you're looking for:

  A <- 42
  get("A")
  ## [1] 42

The sos package does a pretty good job, but your query needs to be 
fairly narrow or the result list will be really long.  I don't think it 
would have found get() in the top hits given the words in your original 
question.  Some questions need intelligence to interpret, not just 
pattern matching.

Other than asking on this list, there's stackoverflow.com to get humans 
involved in the search.
