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?
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. Duncan Murdoch

Dear members,
I think the following question is rudimentary, but I couldn't find an answer in the Internet.
Suppose there is an object A, and ls() lists it as "A". How do 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
Thank you,
Yours sincerely,
