Split the Elements of a Character Vector

Split the elements of a character vector x into substrings according to the matches to substring split within them.
This is a verbatim copy of the base R function strsplit, but with a split default of "" and returning a vector instead of a list, when x had the length 1.

StrSplit(x, split = "", fixed = FALSE, perl = FALSE, useBytes = FALSE)

Arguments

x

character vector, each element of which is to be split. Other inputs, including a factor, will give an error.

split

character vector (or object which can be coerced to such) containing regular expression(s) (unless fixed = TRUE) to use for splitting. If empty matches occur, in particular if split has length 0, x is split into single characters. If split has length greater than 1, it is re-cycled along x.

fixed

logical. If TRUE match split exactly, otherwise use regular expressions. Has priority over perl.

perl

logical. Should Perl-compatible regexps be used?

useBytes

logical. If TRUE the matching is done byte-by-byte rather than character-by-character, and inputs with marked encodings are not converted. This is forced (with a warning) if any input is found which is marked as "bytes" (see Encoding).

Details

See strsplit for the details.

Value

A list of the same length as x, the i-th element of which contains the vector of splits of x[i].

If the length x was 1 a vecotor with the splits will be returned.

Examples

noquote(StrSplit("A text I want to display with spaces"))
#>  [1] A   t e x t   I   w a n t   t o   d i s p l a y   w i t h   s p a c e s

# the same as ...
noquote(strsplit("A text I want to display with spaces", NULL)[[1]])
#>  [1] A   t e x t   I   w a n t   t o   d i s p l a y   w i t h   s p a c e s
