Adding drop down menu to Choropleth map to select each state and generate new graph type

问题 I've created a Choropleth map and I want to know if it's possible to add a drop down with each state. When you select the drop down the graph changes to a line graph of the number of Bachelor degrees earned over time in that state. A sample of my data: year state statetotal ba_total 0 1984.0 AK 221.0 108.0 1 1985.0 AK 242.0 141.0 2 1984.0 NC 229.0 117.0 3 1985.0 NC 257.0 138.0 4 1984.0 MA 272.0 165.0 5 1985.0 MA 280.0 176.0 6 1984.0 NY 375.0 249.0 7 1985.0 NY 309.0 208.0 This is what I've

Generating spatial heat map via ggmap in R based on a value

问题 I'd like to generate a choropleth map using the following data points: Longitude Latitude Price Here is the dataset - https://www.dropbox.com/s/0s05cl34bko7ggm/sample_data.csv?dl=0. I would like the map to show the areas where the price is higher and the where price is lower. It should most probably look like this (sample image): Here is my code: library(ggmap) map <- get_map(location = "austin", zoom = 9) data <- read.csv(file.choose(), stringsAsFactors = FALSE) data$average_rate_per_night <

Choropleth map returning undefined

问题 I'm attempting a choropleth map of US Counties, and am essentially using Mike Bostock's example from here https://bl.ocks.org/mbostock/4060606 I am using education instead of unemployment, but otherwise it's the same. I'd like to add just one more piece to it and have the county name display along with the rate. However, when I call the county name, I get "undefined" returned. To be clear 'rate' returns just fine, 'county' shows up undefined. Can anyone help? Thanks! <!DOCTYPE html> <meta

Trouble with get_tract_map function in R choroplthr

问题 I've just installed the new Choroplethr v3.6.0 and am using Ari Lamstein's blog tutorial to practice, as well as learning R, so I'm still learning to read errors. All the example code works for me, but when I try substituting "georgia" for "new york" I get an error: Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, : Cannot open layer In addition: Warning message: In unzip(file_loc, exdir = cache_dir, overwrite = TRUE) : error 1 in extracting from zip file

Python Folium Choropleth Map KeyError: None

由 馋奶兔 提交于 2020-01-04 05:29:09
问题 I'm interested in creating Choropleth map with Python on a county level. When I run my code without trying to bind data to it I get the county lines drawn in beautifully. However whenever I try to bind my data I get KeyError: None. From my searching it appeared as though this is due to values in the GeoJson not matching up with the values in the data file... but I went in manually and checked and have already edited the data so there are the exact same number of rows and exact same values...

Is there a way that I can manually control the thresholds between various range on choroplethr?

问题 I would like to be able to manually control the thresholds between population ranges on choroplethr package. library(choroplethr) data(df_pop_county) data(continental_us_states) county_choropleth(df_pop_county, state_zoom = continental_us_states) 回答1: You can use cut to create the custom breaks: # rename the original "value" column if you don't want to write over it names(df_pop_county) <- c("region", "original_value") # define the breaks you want df_pop_county$value <- cut(df_pop_county[[

Create choropleth map from coordinate points

由 你离开我真会死。 提交于 2020-01-02 10:30:32
问题 I have a data frame consisting of multiple data points with specific geocoordinates (latitude and longitude). I'm looking to create a choropleth-style world map where geographical regions are shaded according to how many data points fall within the boundaries of the region. Is there a simple way to accomplish what I'm trying to do in R, preferably using the "maps" package's world map and the "ggplot2" map-plotting functions? Here is a minimally reproducible result of what I have: library

R Shiny leaflet addPolygons (colors are not showing)

问题 I hope you can help me. I have created a choropleth Map with Leaflet. I merged my (dataframe with countries and a random score) and a Shapefile with the Polygon data. So far it is working, however if I implement it in R-Shiny, the map is showing, but with no color. There is also no error showing. Anyone knows why? My code: ui <- fluidPage( leafletOutput("map") ) shinyServer(function(input, output) { output$map <- renderLeaflet({ test_map }) }) global.R tmp <- tempdir() url <- "http://www
