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.

See Also:

     String manipulation with `as.character', `substr', `nchar',
     `strsplit'; further, `cat' which concatenates and writes to a
     file.

Examples:

     paste(1:12) # same as as.character(1:12)
     paste("A", 1:6, sep = "")
     paste("Today is", date())
