(not sure this is the right place for this comment. If this is not, I apologize).
I have a caveat with the example of section
"4.2.3 Linking with other htmlwidgets"
The example seems dependent upon
install_github("rstudio/leaflet#346")
otherwise, if I just install
install_github("rstudio/leaflet")
I get blue color for points on the right map when selecting on the left scatterplot (where points are red or
the selected color), which is inconvenient as selected points cannot be identified on the map.
As this type of linked brushing is very important for me, I would like to know if this code will be
valid for future standard releases of leaflet: sticking to #346 might not be possible in the future or interfere with newer improvements.
Thanks
