)

Arguments

grid	A spatial grid to split the data within
events	A feature collection of points representing the events points
lines	A feature collection of linestrings representing the network
bw_net	The fixed kernel bandwidth for the network dimension
bw_time	The fixed kernel bandwidth for the time dimension
trim_bw_net	The maximum size of local bandiwidths for network dimension
trim_bw_time	The maximum size of local bandiwidths for time dimension
method	The method to use when calculating the NKDE
kernel_name	The name of the kernel to use
max_depth	The maximum recursion depth
div	The divisor to use for kernels
tol	A float indicating the spatial tolerance when snapping events on lines
digits	The number of digits to keep
sparse	A Boolean indicating if sparse matrix should be used
verbose	A Boolean indicating if update messages should be printed

Value

A vector with the local bandwidths
