Calculate toxic release covariates
Description
Calculate toxic release values for polygons or isotropic buffer point
locations. Returns a data.frame
object containing locs_id
and variables for each chemical in from
.
Usage
calculate_tri(
from = NULL,
locs,
locs_id = "site_id",
radius = c(1000L, 10000L, 50000L),
geom = FALSE,
...
)
Arguments
from |
SpatVector(1). Output of |
locs |
sf/SpatVector. Locations where TRI variables are calculated. |
locs_id |
character(1). Unique site identifier column name.
Default is |
radius |
Circular buffer radius.
Default is |
geom |
FALSE/"sf"/"terra".. Should the function return with geometry?
Default is |
... |
Placeholders. |
Value
a data.frame or SpatVector object
Note
U.S. context.

locs_id = "id",
radius = c(1e3L, 1e4L, 5e4L)
