\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).
