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.
