urbnmapr | State and county maps with Alaska and Hawaii | Data Visualization library

I am working to use r's ggplot to recreate a graphic originally created in python. The graphic uses a color scale specified via RGB colors. When I create my graphic using the same RGB colors they don't render properly in my Windows 10/Rstudio set up. Below I show the legend rendered correctly and the rendering my r script produces. It seems there is too much yellow coming through the colors.

I don't know where to begin to try to determine why the specified colors are not rendering into the same colors as the example image that I have. What suggestions do you have to try to troubleshoot this?

My reproducible example is below.

I have a data set of latitude/longitude points that seek to convert to a simple feature (sf) in R. My goal is to plot these locations on a US map with polygons retrieved from the urbnmapr library.

Plotting with our a geographic reference, as shown in the code, results in all points being displayed.

When the points are plotted using geom_sf() they end up in South Dakota. It seems the latitude/longitude points are not being converted into the correct coordinate reference system, despite what I think is the correct use of the st_as_sf() function.

What correction needs to be made to this code to show the distribution of wind turbine locations properly on the US map?

I'll apologize in advance that the example below isn't "minimal" but I haven't been able to reproduce this behavior except in the particular instance of my full data set.

I asked this question before here and thought I had found the answer, but the behavior has returned and is vexing me. Basically I have a script that reads daily COVID-19 case numbers and produces maps where the counties are color-coded by the percent of the population infected. The script produces five maps, a national one and one for each of the four official census regions: northeast, midwest, south and west. To cut down on size, the below is just the national and widwest maps.

My original script actually produces animated gifs showing the spread of the disease, but they take a long time to render. The below version just gives a single plot of the most recent data and should run pretty quickly.

I've used a dput in the below script to avoid you having to read a file and geocode locations (I commented out the code) but there is still a large csv file of county populations that has to be read in. I have posted it at pastebin here.

I've been producing animated maps showing the progression of COVID case data. In the interest of producing a minimal example I have skinnied the code down to the below, which only produces one frame. In practice I also read a number of csv files. I've tried to eliminate that in this example, but there is still one with county population data. I have posted it at https://pastebin.com/jCD9tP0X

I am creating a geographic map of data using ggplto2 and it's geom_sf capability. Ultimately, I'm will create an animation of data using gganimate. As such, I'm hoping to keep the placement of the logo within the functions of the ggplot2 library.

I'd like to place a logo in the lower-left corner of the map. When I use the annotation_raster function it's not obvious what the " location (in data coordinates) giving the horizontal location of raster" [see https://ggplot2.tidyverse.org/reference/annotation_raster.html] should be in this case. In the examples provided the coordinates are x & y on an xy plot.

using xmin=-Inf and ymin=-Inf anchors the image in the lower-left corner. What values of ymax and xmax should be used to place the image with a small size that does not impinge on the map?

The example code is below.

With lots of help from this forum, I had been generating animated maps of covid-19 data for the past couple of days for work. Minus a number of overlays that my office has requested, the basic script I was using is

I'm trying to add an outline of US states to a choropleth of county data using ubrbanmapr. I can either plot state outlines or the county choropleth, but not the county choropleth with state outlines. Any guidance is appreciated.

The code:
