I would like to prepare a plot using the parameters in the columns to create the levels. I have been able to use mask to accomplish the major parts of my needs, but I am still missing a step.
The data contains the important data columns are as follows:
Subject, Day, ParameterID, Parameter Value, LLQ, HLQ, Parameter Units
Using masks on Subject and ParameterID, I have made a plot that can select each Subject and each parameter and plot the data, the Hi and Low Control lines, R^2 and regression line. The Title has the Subject name and Parameter ID; The x title is the Day and the Y currently has the parameter, but I would also like to include the parameter units. Those can vary between test sites so it needs to be flexible and part of the units column. I have thought of concatenating the parameter and units columns, while it is ok for the y title, it is messy for the plot title.
Thanks,
Charlie
PS: I have enjoyed the youTube replays of the Webinars and have learned a great deal from those.
