I want a map with points (and other geom_* layers) on it. I get the map, but instead of the points all I get is a warning: Message d'avis : Removed 3 rows containing missing values (geom_point).Here is a reproducible exemple: library(ggmap) library(ggplot2) d <- data.frame(lat=c(50.659631, 50.607213, 50.608129), lon=c(3.09319, 3.011473, 3.031529)) Lille <- get_map("Lille,France", zoom=12) p <- ggmap(Lille) p <- p + geom_point(data=d, aes(lat, lon)) pLooking in the output of ggplot_build(p)I see a layer with NAs for x and y, but I do not get why the data from d is not considered. When using ggplot() instead of ggmap(), I do get the points. But I do need the map too :) So, how can I get a map with points over it? (责任编辑：) |
