R help - Feb 2009 - How to transfer a list of space delimited character elements into a char vector?

My dear R-helpers:

I am a novice in R and have the following text string manipulation question.

Is there a function that performs the job described below?
Say,
wanted_output <- c("ab", "cd", "ef")
#the function_wanted can generate  c("ab", "cd",
"ef") using ab cd ef as the
single input argument
wanted_output <- function_wanted(ab cd ef)


Motivation: I have a very long list of character elements (like, ab cd ef gg
ww kwfl ......),

I try to avoid
typing "," between two adjacent elements,
typing " in front of the first element,
and typing " right after the last element.
when using them to generate a character vector.

Many Thanks in advance.

Hi,

something like this perhaps,


create_string <- function(.s){
	result <- read.table(textConnection(.s))
	sapply(result, as.character)
}

(test <- create_string("ab cd ef"))

hope this helps
