Arguments

polygons

sf

filt_col

Character name of column in polygons to filter on (or NULL for no filter)

filt_level

Level(s) of filt_col to filter

buffer

Numeric (or FALSE). Distance to buffer in units of buf_crs

bbox

Logical. Return a bounding box around the result?

clip

sf. If not null, this will be used to clip back the original polygons +/- filtered +/- buffered +/- bbox. CHECK both CRS and clip_buf

clip_buf

Numeric (or FALSE). Distance to buffer clip in units of clip

buf_crs

EPSG code to use when buffering

out_crs

EPSG code for coordinate system of result
