\title{Install an expression as a function}
\usage{
installExprFunction(expr, name, eval.env = parent.frame(2), quoted = FALSE,
  assign.env = parent.frame(1), label = deparse(sys.call(-1)[[1]]),
  wrappedWithLabel = TRUE, ..stacktraceon = FALSE)
}
\arguments{
\item{expr}{A quoted or unquoted expression}

\item{name}{The name the function should be given}

\item{eval.env}{The desired environment for the function. Defaults to the
calling environment two steps back.}

\item{quoted}{Is the expression quoted?}

\item{assign.env}{The environment in which the function should be assigned.}

\item{label}{A label for the object to be shown in the debugger. Defaults to
the name of the calling function.}

\item{wrappedWithLabel, ..stacktraceon}{Advanced use only. For stack manipulation purposes; see
\code{\link{stacktrace}}.}
}
\description{
Installs an expression in the given environment as a function, and registers
debug hooks so that breakpoints may be set in the function.
}
\details{
This function can replace \code{exprToFunction} as follows: we may use
\code{func <- exprToFunction(expr)} if we do not want the debug hooks, or
\code{installExprFunction(expr, "func")} if we do. Both approaches create a
function named \code{func} in the current environment.
