adding many polyLines in R leaflet -

-

is there way add poly lines @ once. doing way below slow...

at moment, i'm doing through loop follows:

leafletproxy("mainmap") %>%            addpolylines(lng = currentgeodata[i,c("custlon","sercenterlon")],                         lat = currentgeodata[i,c("custlat","sercenterlat")],                        color = "red")

so each time lngvariable vector of length 2 , lat variable same.

as long you're going through entire column, don't need index i:

leafletproxy("mainmap") %>%          addpolylines(lng = currentgeodata[c("custlon","sercenterlon")],                     lat = currentgeodata[c("custlat","sercenterlat")],                    color = "red")
