Calculate speed along a path

Description

calc_dist calculate speed between locations, taking a dataframe as input. Speed can also be smoothed over the two steps before and after the each point.

Usage

calc_speed(
  x,
  coord.names = c("x", "y"),
  timecol = "dateTime",
  smoothed = FALSE,
  units = "hour"
)

Arguments

x	data.frame with locations
coord.names	names of coordinates column in x
timecol	names of POSIXct time column
smoothed	whether speed are smoothed or not
units	units for time calculation. Default "hour"

Value

vector of distance
