* Implement reactiveConsole(). Fixes #2518 * Also includes makeReactiveBinding tweaks * use `reactiveConsole()` to provide a nicer example * simplified the implementation using `reactiveVal()` * remove from documentation indexes since you probably don't want to be promoting this function

\description{
|
|
Turns a normal variable into a reactive variable, that is, one that has
|
|
reactive semantics when assigned or read in the usual ways. The variable may
|
|
already exist; if so, its value will be used as the initial value of the
|
|
reactive variable (or \code{NULL} if the variable did not exist).
