问题 Is there any package available on npm for google maps?

问题 I'm trying to make a world map with a custom legend on the right side. The legend should be with the prepared text on the left and the generated numbers on the right. I tried but to no avail. I need help My code is as follows: library(dplyr) library(ggplot2) library(ggrepel) library(rworldmap) world_map_without_antarctica <- getMap()[-which(getMap()$ADMIN=='Antarctica'),] #get data from web world_map_without_antarctica_t <- fortify(world_map_without_antarctica) Data <- data.frame( "lon"=c(17

问题 I'm trying to transpose a map so that: [x: y, w: y, a: b] becomes [y: [x, w], b: a] (all variables are strings) Doing something like ["x": "y", "w": "y", "a": "b"].collectEntries { [it.value, it.key] } gets me part way, but stomps on the first new value for "y". I only get: [y:w, b:a] What is the best way to slurp up the new values into an array for their common new key? Thanks for any help or suggestions. 回答1: I hope this helps : def map = ["x": "y", "w": "y", "a": "b"] map.groupBy{ it.value

问题 I tried everything I found on the web, Stackoverflow and Github, and I still can't make it. I want to make a custom marker with a custom icon, but with my code below I always got an error : 'TypeError: options.icon.createIcon is not a function' Here is my code (no error on the paths to folders, everything is in src/js or src/img) Icon.js import L from 'leaflet'; const iconPerson = L.Icon.extend({ options: { iconUrl: require('../img/marker-pin-person.svg'), iconRetinaUrl: require('../img

问题 I have a PRICE_MAPPER table at my DB It has around 5000 entries Price is determined on 3 entry types A B C ---> 300 (col1:A , col2:B , col3:C , colPrice:300) X Y Z ---> 500 .. and around 5000 of such entries (3 unique combinations determining a price) Planning to put these in a MAP at my Nodejs application Concern : I need advice, putting such a heavy data at my Nodejs application, would that be good decision or bad, as Nodejs is not for memory intensive tasks. I can cache this data at REDIS

问题 I'm trying to replicate using ggplot2 , an earlier question i had using leaflet. I'm trying to merge two palettes where one is used if my variable is below a certain threshold and another if above a certain threshold. As I did with my leaflet question my final plot doesn't seem to be correct. I also want to convert the factor legend to a continuous one. Example code: library(sf) library(leaflet) library(RColorBrewer) # preparing the shapefile nc <- st_read(system.file("gpkg/nc.gpkg", package=
