问题 I'm trying to use choroplethr to make a map at the county level. Currently, I have 3 categorical integers (1, 2, 3) in my csv under the column value which vary depending on each county. The region column contains county fips. I want to display the following values as the respective label , color (value = label = color): 0 = "None" = "white", 1 = "MD" = "#64acbe", 2 = "DO" = "#c85a5a", 3 = "Both" = "#574249", I've tried several combinations of scale_fill_brewer without the results I'm looking

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

问题 I'm struggling to customize and find the right code to structure the choropleth map that I am attempting to make of profit of a business by county in a specific state. What I have done so far is be able to plot my code, albeit with a color palette that I don't want and breaks that are undesirable as well. library(choroplethr) library(ggplot2) county <- data.frame(region = c(19001,19013,19017,19019,19021,19023,19033,19035), value=c(-37102,-41052,35016,-13180,-8062,6357,-46946,-5380)) county

问题 I am trying to format a Choropleth Map of the United States to a specific color and unfortunately, when using scale_fill_brewer to change the color; only 48 of the states do (Hawaii and Alaska do not). Is it possible to know if I can implement the coloring to Hawaii and Alaska as well? library(choroplethr) library(choroplethrMaps) library(ggplot2) data(df_pop_county) county_choropleth(df_pop_county, title = "Title1", legend = "Top 20% of Index", num_colors = 9) + geom_polygon(aes(fill=value),

问题 I'm trying to replicate the maps shown in this short example (Choroplethr v3.6.0 is now on CRAN) for California, but I'm having trouble with the tract_choropleth function for areas that are not in NY. I get the error message below. I'm able to import the underlying tract data for all areas, but I'm having trouble mapping the non-NY ones. Thanks in advance. # Load all packages (DONE) # Install api key (DONE) # Get Tract-Level Demographics ca_stats = get_tract_demographics("california") #

问题 I am trying to make a choropleth of very simple data, and it's kind of a pain in the neck. I have the following zip codes in the Eastern USA. This is made up data but you get the idea. Zip Freq 11101 10 10014 15 11238 400 etc. for about 100 rows. Values of Freq range from 0-1000, and these are the ones I would like to use to determine the color of each zipcode. I would ideally also like the map to focus on the Eastern USA instead of the whole country. I want to make a choropleth with this
