bw_checks: Check function for parameters in bandwidth selection methods

In spNetwork: Spatial Analysis on Network

Check function for parameters in bandwidth selection methods

Description

A check function for bandwidth selection methods raising an error if a parameter is not valid

Usage

bw_checks(
  check,
  lines,
  samples,
  events,
  kernel_name,
  method,
  bws_net = NULL,
  bws_time = NULL,
  arr_bws_net = NULL,
  arr_bws_time = NULL,
  adaptive = FALSE,
  trim_net_bws = NULL,
  trim_time_bws = NULL,
  diggle_correction = FALSE,
  study_area = NULL
)

Arguments

check	A boolean indicating if the geometries must be checked
lines	A feature collection of linestrings representing the underlying network
samples	A feature collection of points representing the sample location
events	a feature collection of points representing the events
kernel_name	The name of the kernel to use
method	The name of the NKDE to use
bws_net	An ordered numeric vector with all the network bandwidths
bws_time	An ordered numeric vector with all the time bandwidths
arr_bws_net	An array with all the local netowrk bandwidths precalculated (for each event, and at each possible combinaison of network and temporal bandwidths). The dimensions must be c(length(net_bws), length(time_bws), nrow(events)))
arr_bws_time	An array with all the local time bandwidths precalculated (for each event, and at each possible combinaison of network and temporal bandwidths). The dimensions must be c(length(net_bws), length(time_bws), nrow(events)))
adaptive	A boolean indicating if local bandwidths must be calculated
trim_net_bws	A numeric vector with the maximum local network bandwidth. If local bandwidths have higher values, they will be replaced by the corresponding value in this vector.
trim_time_bws	A numeric vector with the maximum local time bandwidth. If local bandwidths have higher values, they will be replaced by the corresponding value in this vector.
diggle_correction	A Boolean indicating if the correction factor for edge effect must be used.
study_area	A feature collection of polygons representing the limits of the study area.
