Hi Bruce,

Sounds like that you are looking for sp:::over().

HTH,

Hi all,
Back in January I inquired about R packages to extract associations of 
spatial layers.
The one reply related to raster data.

The shape file layers I am working with are vector layers.
I need to revisit this to see what I can do.
I have species distribution layers (Vector shape files) and 
ecological/habitat layers (also vector shp files) and need to derive the 
species associations for each ecosystem/habitat layer where they occur 
and extract the resulting data tbls.

Any other suggestion I might try using R based packages?

Again I am traveling and do not have access to my workstation ArcMap so 
need to derive these overlap associations using an R based approach.

Thanks all.
Bruce

I have grown to prefer the sf package, I've found it to be much cleaner and
straightforward than working with sp. You can use sf::st_intersection and
convert the resulting sf layer to a data frame.
