Character operations, strsplit()

Dear group, 

could some one help me how i can split a string into
pieces and access them.

For example:

test = "this is a test"
typeof(test)

[1] "character"

strsplit(test,split='is')

[[1]]
[1] "th"      " "       " a test"


Now I want to get test into : a vector and another
object as list


Also, could you please point out some good tutorials
on character manipulations. 

Thank you.
