dextract.lab: Extract a subset of data from a trackdata object

Description

Extract a subset of data from a trackdata object according to the label in the parallel label vector.

Usage

dextract.lab(dataset, labs, labtype = unique(labs))

Arguments

dataset

A trackdata object returned from track.

labs

A vector of labels parallel to trackdata$index, i.e. one for each segment in the trackdata.

labtype

A vector of labels for which data is to be extracted.

Value

• A trackdata object which is a subset of trackdata containing only the data for those labels in labtype. The result has the same components as the input trackdata:
• data
  A vector or matrix of numerical data.
• index
  A two column matrix giving the start and end indeces into the data vector for each segment.
• ftime
  A two column matrix giving the start and end times for each segment.
