reactiveValuesToList: Convert a reactivevalues object to a list
In sheikhbarabas/shiny: Web Application Framework for R

This function does something similar to what you might as.list to do. The difference is that the calling context will take dependencies on every object in the reactivevalues object. To avoid taking dependencies on all the objects, you can wrap the call with isolate().

1	reactiveValuesToList(x, all.names = FALSE)

`x`	A reactivevalues object.
`all.names`	If `TRUE`, include objects with a leading dot. If `FALSE` (the default) don't include those objects.

values <- reactiveValues(a = 1)
## Not run: 
reactiveValuesToList(values)

## End(Not run)

# To get the objects without taking dependencies on them, use isolate().
# isolate() can also be used when calling from outside a reactive context (e.g.
# at the console)
isolate(reactiveValuesToList(values))
