Returns track attributes values.
gtrack.attr.export(tracks = NULL, attrs = NULL)a vector of track names or 'NULL'
a vector of attribute names or 'NULL'
A data frame containing track attributes values.
This function returns a data frame that contains track attributes values. Column names of the data frame consist of the attribute names, row names contain the track names.
The list of required tracks is specified by 'tracks' argument. If 'tracks' is 'NULL' the attribute values of all existing tracks are returned.
Likewise the list of required attributes is controlled by 'attrs' argument. If 'attrs' is 'NULL' all attribute values of the specified tracks are returned. The columns are also sorted then by "popularity" of an attribute, i.e. the number of tracks containing this attribute. This sorting is not applied if 'attrs' is not 'NULL'.
Empty character string in a table cell marks a non-existing attribute.
