This could be caused by a few things:

• The file doesn't exist in the working directory
• R doesn't have permission to read the file

R is looking for "data/brussels.tif" in your working directory, which you can see by running getwd(). The working directory can change (for example, when you run setwd()).

file.exists("data/brussels.tif") will return TRUE if "data/brussels.tf" exists in the current wd, or FALSE if it does not. If it returns FALSE, that's your problem. If it returns TRUE, it may be that R can see the file, but doesn't have permission to read it.

It should work if you convert your population data into a numeric column and join it to your shapefile. This code worked for me:

Your elmat %>% reshape2::melt() %>% ggplot() pattern causes the Var1 and Var2 columns of the plot input to be row and column numbers instead of coordinates. Also, your samplelocs were sampling values instead of cells from the localtif objects it seems.

I adressed these two points in the code below:

Problem solved (make sure ffmpeg path is well set up though) :

Modify your code to:

You could have a look at the elevatr package, which will give you the raster you want:
