You can install this package from CRAN
or GitHub
:
# From CRAN install.packages('hchinamap', build_vignettes = TRUE) # From GitHub devtools::install_github('czxa/hchinamap', build_vignettes = TRUE) # or use git devtools::install_git("https://github.com/czxa/hchinamap.git", build_vignettes = TRUE)
I made a demo datasets for this package. You can load it by following method:
dir <- tempdir() download.file('https://czxb.github.io/br/chinadf.rda', file.path(dir, 'chinadf.rda')) load(file.path(dir, 'chinadf.rda'), verbose = TRUE)
library(dplyr) library(magrittr) library(hchinamap) china <- chinadf %>% dplyr::filter(region == "China") hchinamap(name = china$name, value = china$value, width = "100%", height = "400px", title = "Map of China", region = "China")
Modify the maximum and minimum colors:
china <- chinadf %>% dplyr::filter(region == "China") hchinamap(name = china$name, value = china$value, region = "China", width = "100%", height = "400px", title = "Map of China", minColor = "#f1eef6", maxColor = "#980043")
For example, map of Anhui:
anhui <- chinadf %>% dplyr::filter(region == "Anhui") hchinamap(name = anhui$name, value = anhui$value, width = "100%", height = "500px", title = "Map of Anhui", region = "Anhui")
Map of Guangdong:
gd <- chinadf %>% dplyr::filter(region == "Guangdong") hchinamap(name = gd$name, value = gd$value, width = "100%", height = "400px", title = "Map of Guangdong", region = "Guangdong")
Map of Heilongjiang:
hlj <- chinadf %>% dplyr::filter(region == "Heilongjiang") hchinamap(name = hlj$name, value = hlj$value, width = "100%", height = "400px", title = "Map of Heilongjiang", region = "Heilongjiang")
If there are multiple map charts created by this package in a RMarkdown document, use topic parameters carefully, because the charts may interfere with each other.
sx <- chinadf %>% dplyr::filter(region == "Shaanxi") hchinamap(name = sx$name, value = sx$value, width = "100%", height = "400px", title = "Map of Shaanxi", region = "Shaanxi", theme = "darkunica", titleColor = "white")
Here if a very simple 'shiny' example:
dir <- system.file("examples", "hchinamap", package = "hchinamap") setwd(dir) shiny::shinyAppDir(".")
