Make a reactive variable

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 NULL if the variable did not exist).

Usage
makeReactiveBinding(symbol, env = parent.frame())
Arguments
symbol
A character string indicating the name of the variable that should be made reactive
env
The environment that will contain the reactive variable
Value

  • None.

Examples
a <- 10
makeReactiveBinding("a")
b <- reactive(a * -1)
observe(print(b()))
a <- 20
