Description

HeatMaker - Calculates smoothed dwell time at each coodinates.

Usage

SmoothDwell(smooth.data, x.vec = NULL, y.vec = NULL, sigma = 9,
  n = 57, quant = 0.95, to.plot = FALSE)

Arguments

smooth.data	A data.frame contains x and y coordinates name of x coordinates vector should contain "x" or "X" column name of y coordinates vector should contain "y" or "Y"
x.vec	The grid of x-axis for the heatmap. Defaults to seq(min(x), max(x), 1)
y.vec	The grid of y-axis for the heatmap. Defaults to seq(min(y), max(y), 1)
sigma	The standard deviation of the Gaussian smoothing kernel, controls the level of the smoothing (larger, the heatmap will be smoother)
n	The filter size is n * n
quant	Quantile threshold, returns the > quant local maxima
to.plot	Flag, if TRUE will also plot the heatmap

Value

The function returns a list with following objects:

smooth.dwell.time

a data.frame, x, y, smooth.dwell.time. For each cell coordinates the smoothed dwell time spent

maxpoint

coordinates of local maxima above the predetermined threshold
