catchment_convenient: find upstream catchments

In konradmayer/trlboku: Tree Ring Lab BOKU - a lab internal R function collection

Description

convenient, but slower, version of catchment where only the path to the digHAO folder needs to be supplied. If you want to find catchments for multiple points in a loop use catchment instead as catchment_convenient() loads the digHAO data at each function call.

Usage

catchment_convenient(
  path_digHAO,
  lonlat,
  proj4string = sp::CRS("+init=epsg:4326"),
  make.plot = TRUE,
  ...
)

Arguments

path_digHAO	path to the digHAO directory as character string
lonlat	a numeric vector of length 2 with the longitue and latitude of a mappoint
proj4string	the proj4string of the provided lonlat
make.plot	logic
...	additional plotting arguments such as plot title etc.

Value

a list with index values as first and HYDROIDs as second member
