I was trying out rMaps package, which uses leaflet js api. While plotting a coordinate c(3.09407,101.504961), rmaps/leaflet point is off from the actual point. 

require(rMaps)
map <- Leaflet$new()  
map$setView( c(3.09407,101.504961))   
map$marker(c(3.09407,101.504961))     
map

is this a known issue? Does leaflet requires some correction to get exact plot.

  • It is a bug in rMaps, and NOT Leaflet. It happens due to rounding when converting to JSON. There is a pull request with a fix, which I will be merging shortly.
