[R] options other than regex

[Alex Zarebski]

The stringr package might beof interest to you (and I think magrittr makes
it more readable).

> library(stringr)
> library(magrittr)
> '10110111' %>% str_split('') %>% unlist %>% str_flatten('.')
[1] "1.0.1.1.0.1.1.1"

Note that the unlist is there because we are only applying this to a single
string.
If you were to apply this to a character vector you could loose the unlist
and sapply the flatten.
