Substring and strsplit

Dear R People:

I am trying to split a character vector into a set of individual
letters:

Ideal:
x3 <- c("dog")
"d" "o" "g"

I tried the following:
strsplit(x3)
Error in strsplit(x3) : argument "split" is missing, with no default
strsplit(x3,1)
[[1]]
[1] "dog"

I know that this is incredibly simple, but what am I doing wrong?

Either Windows or Linux 2.3.1

Thanks in advance!

Sincerely,

This is the first example on the help page for strsplit.

Use '' as parameter to strsplit
x3 <- 'dog'
strsplit(x3, '')
[[1]]
[1] "d" "o" "g"

What is the problem you are trying to solve?
you can also use substring(), e.g.,

substring(x3, 1:nchar(x3), 1:nchar(x3))

Best,
Dimitris

If you are using 'only' English then

str <- "dog"
strsplit(str,NULL)[[1]]

works perfectly and it is fast.

But if you also dealing with Unicode character have a look at

strings:decomposestring
