Concatenate Strings

Description

Concatenate vectors after converting to character.

Usage

paste(..., sep = " ", collapse = NULL)

Arguments

... one or more R objects, to be coerced to character vectors.
sep a character string to separate the terms.
collapse an optional character string to separate the results.

Details

paste converts its arguments to character strings, and concatenates them (separating them by the string given by sep). If the arguments are vectors, they are concatenated term-by-term to give a character vector result.

If a value is specified for collapse, the values in the result are then concatenated into a single string, with the elements being separated by the value of collapse.

Value

A character vector of the concatenated values. This will be of length zero if all the objects are, unless collapse is non-NULL, in which case it is a single empty string.
