emuR track data object
Description
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.
Format
The data.frame
has the following columns:
- $sl_rowIdx
column to indicate
emuRsegs
row index that the value belongs to- $labels - $sampleRate
duplicated information of
emuRsegs
row entries- $times_rel
relative time stamps of sample values in milliseconds
- $times_orig
absolute time stamps of sample values in milliseconds
- $T1 - $TN
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.
Methods
The following methods are implemented for emuRtrackdata objects:
- cut
Function to extract a
emuRtrackdata
object from an emuRtrackdata at a single time point or between two times
