Flatten a String
Joins the elements of a character vector into one string.
stri_flatten(str, collapse = "", na_empty = FALSE, omit_empty = FALSE)
str |
a vector of strings to be coerced to character |
collapse |
a single string denoting the separator |
na_empty |
single logical value; should missing values
in |
omit_empty |
single logical value; should missing values
in |
The stri_flatten(str, collapse='XXX') call
is equivalent to paste(str, collapse='XXX', sep='').
If you wish to use some more fancy (e.g., differing)
separators between flattened strings,
call stri_join(str, separators, collapse='').
If str is not empty, then a single string is returned.
If collapse has length > 1, then only the first string
will be used.
Returns a single string, i.e., a character vector of length 1.
Other join:
%s+%(),
stri_dup(),
stri_join_list(),
stri_join()
stri_flatten(LETTERS) stri_flatten(LETTERS, collapse=',') stri_flatten(stri_dup(letters[1:6], 1:3)) stri_flatten(c(NA, '', 'A', '', 'B', NA, 'C'), collapse=',', na_empty=TRUE, omit_empty=TRUE)
