Align movement data

align_move.Rd

This function aligns movement data to a uniform time scale with a uniform temporal resolution throughout the complete movement sequence. This prepares the provided movement data to be usable by frames_spatial, which requires a uniform time scale and a consistent, unique temporal resolution for all supplied trajectories.

Usage

align_move(m, res = "minimum", start_end_time = NULL, ..., verbose = TRUE)

Arguments

m

move2 object, which is allowed to contain irregular timestamps and diverging temporal resolutions.

res

either a units object representing the temporal resolution m should be aligned to, or a character being one of 'min', 'max', 'mean' or 'median' to indicate how the target resolution should be derived from m.

start_end_time

NULL (default) or a vector of two POSIXct times (one start time and one end time for alignment). If NULL, the start and end time are retrieved from m and used for alignment.

  • "minimum" to use the smallest temporal resolution of m (default)

  • "maximum" to use the largest temporal resolution of m

  • "mean" to use the rounded average temporal resolution of m

  • "median" to use the rounded median temporal resolution of m

...

deprecated arguments, including digit, unit and spaceMethod.

verbose

logical, if TRUE, messages and progress information are displayed on the console (default).

Value

move2 object, with aligned positions at uniform temporal scale computed from m, ready to be used by frames_spatial.
