plotVelocity: Plot GPS Velocities

In andresgmejiar/lbmech: A Package to Study the Mechanics of Landscape and Behavior

Plot GPS Velocities

Description

Plot the log-probability of the observed velocity data points versus the regressed nonlinear quantile regression

Usage

plotVelocity(
  velocity,
  v_lim = 3,
  v_min = 0,
  slope_lim = 1,
  bins = 100,
  x.bins = bins,
  y.bins = bins
)

Arguments

velocity	The list output to getVelocity.
v_lim	The maximum velocities to plot (y-axis limit). Default is 3 m/s.
v_min	The minimum velocities to plot (y-axis limit). Default is 0.
slope_lim	The maximum slopes to plot (x-axis limits). Default is 1.
bins	Into how many bins are the axes divided?
x.bins	Into how many bins are the axes divided?
y.bins	Into how many bins are the axes divided?

Value

A ggplot object

Examples

# Note that the output results should be senseless since they
# are computed on random data

# If the data contains an 'elevation' or 'z' column
data <- data.table(x = runif(10000,10000,20000),
                   y = runif(10000,30000,40000),
                   elevation = runif(10000,0,200),
                   dt = 120,
                   ID = rep(1:10,each=1000))
velocity <- getVelocity(data = data, z = 'elevation')
plotVelocity(velocity)
