\begin{Description}\relax
Concatenate character vectors.\end{Description}
\begin{Usage}
\begin{verbatim}
paste(..., sep = " ", collapse = NULL)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{...}] one or more \R{} objects, to be coerced to character vectors.
\item[\code{sep}] a character string to separate the terms.
\item[\code{collapse}] an optional character string to separate the results.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
\code{paste} converts its arguments to character strings, and
concatenates them (separating them by the string given by \code{sep}).
If the arguments are vectors, they are concatenated term-by-term to
give a character vector result.

If a value is specified for \code{collapse}, the values in the result
are then concatenated into a single string, with the elements being
separated by the value of \code{collapse}.\end{Details}
\begin{Value}
A character vector of the  concatenated values.\end{Value}

\code{\Link{as.character}}, \code{\Link{substr}}, \code{\Link{nchar}},
\code{\Link{strsplit}}.\end{SeeAlso}
\begin{Examples}
\begin{ExampleCode}
paste(1:12) # same as as.character(..)
paste("A", 1:6, sep = "")
paste("Today is", date())
\end{ExampleCode}
