Read and analyze work loop files from a directorySource:
All-in-one function to import multiple workloop .ddf files from a directory, sort them by mtime, analyze them, and store the resulting objects in an ordered list.
Directory in which files are located
Regular expression used to specify files of interest. Defaults to all .ddf files within file_path
Metadata by which files should be sorted to be in the correct run order. Defaults to
mtime, which is time of last modification of files.
Additional arguments to be passed to
A list containing
analyzed_workloop objects, one for each file that is
imported and subsequently analyzed. The list is sorted according to the
sort_by parameter, which by default uses the time of last modification
of each file's contents (mtime).
Work loop data files will be imported and then arranged in the order
in which they were run (assuming run order is reflected in
Chiefly used in conjunction with
time_correct() if time correction is desired.
Most systems we have encountered record Position data in millimeters
and Force in millinewtons, and therefore this function assumes data are
recorded in those units. Through a series of internal conversions, this
function computes velocity in meters/sec, work in Joules, and power in
Watts. If your raw data do not originate in millimeters and millinewtons,
please transform your data accordingly and ignore what you see in the
