ggpattern | ggplot geoms with pattern fills | Data Visualization library

I am trying to install the ggpattern package from GitHub (https://www.rdocumentation.org/packages/ggpattern/versions/0.2.0)

I've reinstalled R, followed the all steps according to the site, also tried

remotes::install_github("coolbutuseless/ggpattern", force = TRUE)

But I still get:

I made some maps with spatial features from the sf package and used ggpattern to create a striped fill. This worked well for certain polygons, but not for those with holes in it (islands in a lake feature class).

Recently the ggpattern package has been updated to work with polygons with holes (for which I am grateful!), and it no longer gives errors for these features but now the pattern fill is wrong for all features (with and without holes), since it no longer follows the polygon borders but instead fills a rectangle around the polygons.

Here's an example using the rnaturalearth package to show what I mean.

I would like to change the color of a shared color to a different color, let's say red. So far, I am plotting the German federal state Bavaria and touching Austrian states. I get the data from https://gadm.org/download_country.html -

Germany Level 2 - https://biogeo.ucdavis.edu/data/gadm3.6/Rsf/gadm36_DEU_2_sf.rds

Germany Level 1 - https://biogeo.ucdavis.edu/data/gadm3.6/Rsf/gadm36_DEU_1_sf.rds

Austria Level 2 - https://biogeo.ucdavis.edu/data/gadm3.6/Rsf/gadm36_AUT_2_sf.rds

Austria Level 1 - https://biogeo.ucdavis.edu/data/gadm3.6/Rsf/gadm36_AUT_1_sf.rds

Similar questions have been asked before in other forms. Some can be found here and here. However, I cant seem to adapt them when using a facet wrap displaying multiple density plots.

I tried adapting the other examples, but failed... I also tried using the ggpattern package, but when there is a large amount of data, it takes several minutes on my machine to create a plot.

I am trying to create a gradient under the density curve... but with the gradient pointing down. Something like in the example image below:

Some example data to work with:

I've been trying to differentiate between the patient and the medic values of my grouped barplot using ggpattern. I have been trying to have one bar shaded and the other blank but it has not worked out. I keep getting this output:

This is the code I used:

I'm not able to customise the legends I have with ggplot/ggpattern.

1. The "SPEED" legend should not display any pattern (just the 3 colors)
2. The "TYPE" legend should have custom texts instead of 0 and 1

thanks!

code:

I used grid.draw() function of ggnewscale package to get the plot

But it seems the way of download is not the same to ggplot2 type.

I used pdf() to save my plot result in shinyapp.

But when I click the download button the plot result is not picture type or not pdf

It confused me and I viewed several methods(here) but it doesn't work

I also get some advice Here

Here is my reproducible code and data:

I use the code below.

The order of the legends on the right is city, split. How can I reverse the order to split, city? I tried to use order in guides(), but that does not work. How to solve this?

I found the following example that explains how to add patterns to the geom_tile plot but I cannot get my plot to show by following the steps. Attached is a few rows of the data:
