r leatflet addPolygons fill country

[antoine4ucsd]

Hello
I am trying to show a worldmap of data. filling country by my variable. when I plot it, I have an issue with country being cut on one side. is it possible to make sure it does not happen. I tried different zoom and centering but it does not seem to work...

I used these base options

leaf_map_tiles =leaflet::leaflet(world_map,
                           options = leaflet::leafletOptions(attributionControl=F,
                                                             initialTileLayerAttribution="",
                                                             attributionPrefix=" ",
                                                                minZoom = 1.3,center = c(28,13), 
                                                             maxZoom = 4,
                                                             zoom=1.3))

but when I add polygon

leaf_map1 = leaf_map_tiles%>%
        leaflet::addPolygons(stroke = T, 
                             smoothFactor = 0.3,
                             weight = 1,
                            fillOpacity = ~factop(num_site2),
                             fillColor = ~pal2(num_site2),
                             color = "white")

then it shows up like below:

how can I prevent the filled country to be cut and appear on both sides?

also if want to add a tile like this one on top of it:

I do

leaf_map1 = leaf_map_tiles%>%
        leaflet::addPolygons(stroke = T, 
                             smoothFactor = 0.3,
                             weight = 1,
                            fillOpacity = ~factop(num_site2),
                             fillColor = ~pal2(num_site2),
                             color = "white")%>%leaflet::addTiles(tilesURL2)

but the filled countries are always on top even with the tiles (see north of pakistan)

any suggestions?

thank you for your help with both issues!
