updateDFBysPlot {iSPlot} | R Documentation |
updateDFBysPlot is called by updateDF when initializing a gUpdateDataMessage object and the active view is a scatterplot. updateDFBysPlot determines the slot values for the new object by calling the function, getChangeDFData. Then updateDFBysPlot returns the slot values in a list.
