save leaflet map with saveWidget

[Vladislav Fridkin]

How can htmlwidgets::saveWidget be used to save a leaflet map after the map has been 'modified' through leafletProxy calls?

So for example, within the same code block this works:

m <- leaflet() %>% ...

saveWidget(m, "temp.html"...)

However after several leafletProxy calls to add markers, etc, how can the map widget be referred to in saveWidget?
