stkde: stkde.

In karpfen/stkde:

Description

stkde.

Calculates a spatiotemporal kernel density estimation (STKDE) and returns it as a 3D-array

Usage

stkde(xyt_in, hs, ht, x_size, y_size, t_size)

Arguments

xyt_in	data.frame containing the x, y and t coordinates of the input data (projected coordinates).
hs	Spatial bandwidth in m.
ht	Temporal bandwidth.
x_size	Spatial x dimension of output array.
y_size	Spatial y dimension of output array.
t_size	Temporal t dimension of output array.

Value

arma::cube object containing all STKDE values.

Examples

## Not run: 
x <- runif (100) * 100
y <- runif (100) * 100
t <- runif (100) * 100
xyt <- data.frame (x, y, t)
stkde_val <- stkde (xyt_in = xyt, hs = 20, ht = 20, x_size = 15, y_size = 15,
t_size = 15)

## End(Not run)
