\title{Concatenate Strings in a List}
\usage{
stri_join_list(x, sep = "", collapse = NULL)
stri_c_list(x, sep = "", collapse = NULL)
stri_paste_list(x, sep = "", collapse = NULL)
}
\arguments{
\item{x}{a list consisting of character vectors}
\item{sep}{a single string; separates strings in each of the character
vectors in \code{x}}
\item{collapse}{a single string or \code{NULL}; an optional
results separator}
}
\value{
Returns a character vector.
}
\description{
These functions concatenate all the strings in each character vector
in a given list.
\code{stri_c_list} and \code{stri_paste_list} are aliases for
\code{stri_join_list}.
}
\details{
Unless \code{collapse} is \code{NULL}, the result will be a single string.
Otherwise, you get a character vector of length equal
to the length of \code{x}.
Vectors in \code{x} of length 0 are silently ignored.
If \code{collapse} or \code{sep} has length greater than 1,
then only the first string will be used.
}
\examples{
stri_join_list(
stri_extract_all_words(c('Lorem ipsum dolor sit amet.',
'Spam spam bacon sausage and spam.')),
sep=', ')
stri_join_list(
stri_extract_all_words(c('Lorem ipsum dolor sit amet.',
'Spam spam bacon sausage and spam.')),
sep=', ', collapse='. ')
stri_join_list(
stri_extract_all_regex(
c('spam spam bacon', '123 456', 'spam 789 sausage'), '\\\\p{L}+'
),
sep=',')
stri_join_list(
stri_extract_all_regex(
c('spam spam bacon', '123 456', 'spam 789 sausage'), '\\\\p{L}+',
omit_no_match=TRUE
),
sep=',', collapse='; ')
