ggspatial | Enhancing spatial visualization in ggplot2 | Data Visualization library

What I'm trying to do: plot spatial objects with ggspatial::geom_sf(), using coord_sf() or a combination of ggspatial::layer_spatial() and ggspatial::annotation_spatial() to specify the extent of the of the plot.

This ggplot/ggspatial behavior has been described in several posts, but the "solutions" have been just ad-hoc hacks that do nothing to ensure the issue doesn't re-occur. See: Setting limits for x and y using coord_sf after updating ggplot2 Error when plotting latitude and longitude points on US map in RStudio

This code works just fine:

I have species occurrence records plotted as points on a UK map created with ggplot2. In my csv, there is a column for record year - how do I add a filter so that only records from a specific year/year range are plotted rather than everything? Code is below, happy with map design just want to only plot some records!

I am trying to plot species range areas using convex hulls to then calculate the area and create a figure.

There is a well known issue with the 180 degree international dateline that I have been trying to remedy following many examples on SE, e.g:

How to remedy a path that crosses the international dateline with R

This comes close to what I am aiming for but plots in mapview not ggplot2: How to construct/plot convex hulls of polygons from points by factor using sf?

Here is my attempt:

I made a map using ggplot2, ggspatial and sf. I used ggspatial so that I could download open source base maps without relying on Google and needing an API key. The ggspatial annotation_map_tile call downloads a set of tiles that provide the base map. I am trying to white out the map outside of the state I am interested in so that the base map only shows within the state.

Here's my code. The dput for the sf object is at the bottom. When you run it, you see a map of New Mexico with a black line outlining the state. I'd like to make the map white outside of the state.

I have a map of the Northern Hemisphere centered around North America. I would like to draw a red rectangle around the USA (this is part of an inset map) however, I can not seem to get geom_rect to draw the rectangle. Any ideas?

Code to make map:

I am new to using R to make maps. I am trying to make a map of North America (centered on the US) and would like the Great Lakes to be the same color as the ocean color. My current code defaults to having them the same color as the countries/states. Any ideas on how to change their color? Maybe a different base map?

Current code:

I'm trying to manage large datasets or files (e.g., GeoTIFF) on plain R (via terminal) or RStudio (1.4.1106), but both apps crash every time on Linux (Manjaro, x64, core i7, and 8 GB RAM) for some scripts (especially when a raster data is plotted using ggplot2 to produce a high-quality map, as well as a lmer function with random factors using a csv file with ~3000 rows and 6 columns). Probably the issue refers to memory management since all the memory is consumed. To overcome, I tried two packages to limit/increase the memory size, such as "unix" and "RAppArmor". However, if the memory size is limited, all your available RAM was exhausted and the famous message "cannot allocate a vector..." is shown. On the other hand, if the memory size is increased to high levels, R/RStudio simply crashes. On Windows, the following code works like a charm to increase memory size (only needed to plot a raster into ggplot2):

I have a problem with plot contour lines using st_as_sf() in shinyapps.io. I checked all the packages' dependencies and nothing. I know that's in st_as_sf() because in my all data set, some contour plot works and don't have any geometry problem with my stands_extent file.

My plot works very well in local Shiny RStudio:

But after publish on shinyapps.io:

My example below and just only with Unique ID CERROCOROADO_003A the plot work:

I'd like to download inside Shiny a georeferenced PDF file (geoPDF) and for this a need some steps like convert the plot in ggplot format to tiff, populate the spatial coordinates, create a geo tiff, and finally my geoPDF. But several steps in downloadHandler() function in tempdir() directory results always in the error:
