installExprFunction: Install an expression as a function

Description

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

Details

This function can replace exprToFunction as follows: we may use func <- exprToFunction(expr) if we do not want the debug hooks, or installExprFunction(expr, "func") if we do. Both approaches create a function named func in the current environment.
