I have been trying set the extent of spatvector of points.

>records
species longitude latitude
species   -62.076  -16.737
species  -60.630  -19.290

I converted it into a spatvector using the following code

species_M <- vect(records, geom=c("longitude", "latitude"), 
                            crs=crs(shapes))

This resulted in the below figure

As the points are too close to the margin, when I process this spatvector in some packages like nichevol, the point at the top left is missing which means that the extracted value from the raster for that point becomes NA.

So, I would like to get a code for setting an expanded extent for these coordinates.

Please help !!!
