These classes store information gathered by time-depth recorders.
TDRspeed-class: Class TDRspeed
fileObject of class ‘character’, string indicating the file where the data comes from.
dtimeObject of class ‘numeric’, sampling interval in seconds.
timeObject of class POSIXct, time stamp for every
reading.
depthObject of class ‘numeric’, depth (m) readings.
concurrentDataObject of class data.frame, optional
data collected concurrently.
Objects can be created by calls of the form new("TDR", ...)
and new("TDRspeed", ...).
‘TDR’ objects contain concurrent time and depth readings, as well as a string indicating the file the data originates from, and a number indicating the sampling interval for these data. ‘TDRspeed’ extends ‘TDR’ objects containing additional concurrent speed readings.

Since the data to store in objects of these clases usually come from a
file, the easiest way to construct such objects is with the function
readTDR to retrieve all the necessary information.
