问题 Morning, afternoon or evening. I have the following positional data (adjusted from 'Count of sampling points within a grid cell') # Demo data set.seed(123) # lat <- runif(1000, 46.5, 48.5) lon <- runif(1000, 13,16) # pos <- data.frame(lon, lat) Using the following: ggplot(pos, aes(x = lon, y=lat)) + geom_bin2d(bins = 25) + stat_bin_2d(aes(label=stat(count)), bins = 25, position="identity") + scale_fill_gradient(low = "white", high = "red")+ theme_void() gives: Awesome, but, I want to do the

问题 I am trying to plot few countries using leaflet but the countries that it is showing is incorrect. Following is my minimal reproducible example: library(leaflet) library(maps) df <- data.frame(name = c("Afghanistan", "Albania" , "Algeria" , "Armenia"), code = c("AFG", "ALB", "DZA", "ARM"), val = c(5, 10, 15, 20), stringsAsFactors = FALSE) pal <- colorNumeric( palette = "Blues", domain = as.numeric(df$val)) labels <- sprintf( "<strong>Country:%s</strong><br/>Value:%g /", df$name, df$val)%>%

问题 This is my state: const [markers, setMarkers] = useState([]) I initialise a Leaflet map in a useEffect hook. It has a click eventHandler. useEffect(() => { map.current = Leaflet.map('mapid').setView([46.378333, 13.836667], 12) . . . map.current.on('click', onMapClick) }, [] Inside that onMapClick I create a marker on the map and add it to the state: const onMapClick = useCallback((event) => { console.log('onMapClick markers', markers) const marker = Leaflet.marker(event.latlng, { draggable:
