How to split a string into its character vector?

Question

In R I have a string like this:

'hello'

How do I convert it to a character vector like that:

[1] "h" "e" "l" "l" "o"

Answer 1

With stringr:

stringr::str_split("hello","")[[1]]
[1] "h" "e" "l" "l" "o"

Found another possible solution, although this is probably the worst approach:

substring("hello", seq(1,nchar("hello")), seq(1,nchar("hello")))
[1] "h" "e" "l" "l" "o"

Answer 2

While this might not be the most performant solution, this works as expected:

> unlist(strsplit('hello', ''))
[1] "h" "e" "l" "l" "o"

See the documentation of unlist and strsplit for further options.
