I need to erase different vector layers(shapefiles) using R, but I am not sure how to do it in a fast way.

I have 10 different shapefiles and a basemap (also shapefile) that I need to erase my vectors from (I need something equivalent to using the "difference" tool in QGIS).

I know how to do it manually, using the ms_erase tool, but I was wondering if there is an easy way of iterating this process:

output1 <- ms_erase(basemap, vector1)
output2 <- ms_erase(output1 , vector2)
output3 <- ms_erase(output2 , vector3)

I loaded the vectors using the st_read function, so their class in R is data.frame.

Thanks, Ines

How to iterate erasing multiple vectors from another vector using R?
