Add wave height to an AcousticStudy or AcousticEvent
addWaveHeight(x, height, thresh = 3600)the same data as x, with wave height data added. All AcousticEvents will
have height data added to all detector dataframes as column waveHeight
an AcousticStudy to add height data to
either a single numeric value, or a dataframe
with column UTC and either column waveHeight
specifying height (m) at that time, or beaufort specifying
the beaufort sea state at that time
maximum time apart in seconds for matching height to
data, if the closest value is more than thresh apart then the
height value will be set to NA
Taiki Sakai taiki.sakai@noaa.gov
height values will be matched to the data
by using data.table's rolling join with roll='nearest'. After the
join is done, the time difference between the matched rows is checked
and any that are greater than the set threshold are set to NA. This is
done to prevent accidentally matching weird things if an incomplete set
of height data is provided.
data(exStudy)
# need to update database file to local directory
exStudy <- addWaveHeight(exStudy, height=.5)
getClickData(exStudy[1])
