pressureProfileSummary | R Documentation |
The function computes a list of Pc values for the in time provided NN using findNN. It returns file, time, timediff and the Pc valyes as list.
pps(data, time)
data |
the data set to be plotted. It reqires the following attributes: |
time |
specifies the timeslots to be used. |
The function is useful for levelplots. It can be used to make a quality check over a sequence of experiments. At our site, it is used in conjugtion with Eksigent pumps. These devices store a text file at the instrument pc. These files are preprocessed as specified in the file structure.
