\name{installExprFunction}
\alias{installExprFunction}
\title{Installs an expression in the given environment as a function, and registers
debug hooks so that breakpoints may be set in the function.}
\usage{
installExprFunction(expr, name,
eval.env = parent.frame(2), quoted = FALSE,
assign.env = parent.frame(1),
label = as.character(sys.call(-1)[[1]]))
}
\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.}
}
\description{
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.
}
\seealso{
Wraps \code{exprToFunction}; see that method's
documentation for more documentation and examples.
