paste
Concatenate Data to Make Character Data
Description
Returns a vector of character strings
(the result of pasting corresponding
elements of the input vectors together).
If the collapse argument is used,
a single string is returned.
Usage
paste(..., sep = " ", collapse = NULL)
Arguments
| ... |
the input vectors to paste. Can be numeric, logical,
complex, or character.
All arguments are coerced to mode character.
Missing values (NAs) are allowed.
If a name object is passed as an argument,
it is coerced to a character vector of length one.
|
| sep= |
the character string to be inserted between successive
arguments. Can be "" for no space. The default is a single
space.
|
| collapse= |
a character string to use in collapsing the result.
NULL by default, specifying no collapsing.
|
Details
The i-th element of the result is the concatenation of the
i-th elements of the arguments. If the length of any
argument is less than the maximum, elements of that argument are
repeated cyclically. For example, an argument can be a single
element, to appear in each element of the result.
If collapse is given, all strings produced are finally
collapsed into one long string with the collapse string
inserted between elements.
Value
returns a character vector with the length equal to the maximum
of the lengths of the arguments (unless collapse is given,
in which case the length is 1).

paste("no.",1:3)
# [1] "no. 1" "no. 2" "no. 3"
paste(1:3,4:6, sep="-")
# [1] "1-4" "2-5" "3-6"
paste(1:10,collapse="")
# [1] "12345678910"
paste(1:3,4:6, sep="-", collapse="; ")
# [1] "1-4; 2-5; 3-6"
