This function returns a data.frame containing standard TDM (thermal dissipation method)
measurements provided in two different formats. The data is obtained from tdm.data
where \(\Delta V\) measurements are given for Norway spruce (Picea abies Karts.)
growing in a valley in the Swiss Alps. See tdm.data for additional details.
example.data(type = "timestamp")Character string, indicating whether the example data should be
displayed with a timestamp (default = “timestamp”)
or separate year, day of day (“doy”).
A data.frame containing TDM measurements according to a specific type.
This dataset can be applied for testing the functions provided in TREX.
