+Values, @acronym{CSV}} file, or uses manually entered data from the format (x,
+y, weight) and plots the appropriate @acronym{Absolute Concentration Curve,
+@acronym{ACC}} vs @acronym{Line of Independence, @acronym{LOI}} graph and
+@acronym{@acronym{LOI} Minus @acronym{ACC}, @acronym{LMA}} graph.  The main
+function is plotLMA (source file, header) that takes a data set and plots the
+appropriate @acronym{LMA} and @acronym{ACC} graphs.  If no source file (a
+string) was passed, a manual data entry window is opened.  The header parameter
+indicates by TRUE/FALSE (false by default) if the source @acronym{CSV} file has
+a header row or not.  The dataset should contain only one independent variable
+(x) and one dependent variable (y) and can contain a weight for each
+observation.")
