get_n_events: Extract n rainfall events

In RobinKohrs/rainfallR: Extract and manipulate gridded rainfall measurements

Description

This is a very inefficient way to extract a number of rainfall events for each landslide. It is inefficient because it checkes for each month if the number of rainfall events already exceeds the specified number. If not, it will start from the beginning again... Some landslides will have more events than specified, because landslides from the same dates are grouped in order to only load the rasters once into memory. And extraction of rainfall values is done for each landslide on that day until the last landslide exceeeds the specified number of rainfal events

Usage

get_n_events(
  point.data = NULL,
  n_dry = NULL,
  daily_threshold = NULL,
  n.events = NULL,
  ncores = 2,
  date_col = "date",
  id_col = "PIFF_ID",
  save = F,
  savePath = "/dev/null",
  path_rainfall = "/mnt/CEPH_PROJECTS/Proslide/PREC_GRIDS_updated/"
)

Arguments

point.data	sf object of landsldies
n_dry	Number of allowed dry days
daily_threshold	Daily threshold that needs to be exceeded to be considered a rainy day
n.events	how many rainfall events to extract for each landslide
ncores	Number of cores working in parallel
date_col	Character of the column that contains the dates of the landslides
id_col	Character uniquely identifying each landslide
path_rainfall	Character of where the rainfall data is saved
