stri_join_mat {tinycodet} | R Documentation |
Concatenate Character Matrix Row-wise or Column-wise
Description
The stri_join_mat()
function
(and their aliases stri_c_mat
and stri_paste_mat
)
perform row-wise (margin = 1
; the default) or
column-wise (margin = 2
) joining of a matrix of strings,
thereby transforming a matrix of strings into a vector of strings.
Usage
stri_join_mat(mat, margin = 1, sep = "", collapse = NULL)
stri_c_mat(mat, margin = 1, sep = "", collapse = NULL)
stri_paste_mat(mat, margin = 1, sep = "", collapse = NULL)
Arguments
mat |
a matrix of strings |
margin |
the margin over which the strings must be joined.
|
sep , collapse |
as in stri_join. |
Value
The stri_join_mat()
function, and its aliases, return a vector of strings.
