comment How to sum up pixel values in QGIS?
Wrong. That would give you the number of cells. Not the sum of cell values

comment How to sum up pixel values in QGIS?
That is wrong. First, these stats are not always present (depends on the application that wrote the file) and if they are present, you cannot be sure that they are actually correct. Second, the multiplication ignores the possibility that there are No Data values (in which case this computation would be wrong).

comment Convert ESRI Shapefile to Raster using R - biggest polygon area to raster cell value?
Perhaps you could rasterize to a smaller resolution, say 1 m (you will need a lot of patience!), and then aggregate the values using the modal function. It would be easier to help if your example was reproducible AND self contained (no need for downloads).

revised Random-Forest Classification of 10cm Imagery for species-distribution in R (no point-shapes)
fixed the example code. Too complicated, and the use of match was not correct here.

Very inefficient approach. mdsummer's suggestion is the correct answer.
