A emuR track data object is the result of get_trackdata if the
resultType parameter is set to "emuRtrackdata" or the result of
an explicit call to create_emuRtrackdata. Compared to
the trackdata object it is a sub-class of a
data.frame which is meant to ease integration with other
packages for further processing. It can be viewed as an amalgamation of
a emuRsegs and a trackdata object as it
contains the information stored in both objects.
The data.frame has the following columns:
column to indicate emuRsegs row index that
the value belongs to
duplicated information of emuRsegs row entries
relative time stamps of sample values in milliseconds
absolute time stamps of sample values in milliseconds
actual data values (e.g. formant values / F0 values / DFT values / ...)
Note that $labels - $sampleRate as well as $T1 - $TN (where the N in TN is to be read as the n-th T value) refer to multiple columns of the object.
The following methods are implemented for emuRtrackdata objects:
Function to extract a emuRtrackdata object from an
emuRtrackdata at a single time point or between two times
get_trackdata, create_emuRtrackdata
trackdata
