Dear dr Futschik, dear List Members, is there any way to get the same values on y axis for plots produced by "mfuzz.plot2" function in Mfuzz package? I've tried options from plot and plot.default (ylim), but nothing works. Second question, if it's possible to insert one time point (time zero=0) as a first point on plots after "mfuzz" function, so on plots profiles will start from 0, but clustering would be based on points without time zero? I know, I can insert column with time zero to my data, use function "standardise2" with timepoint=0, so time point zero retain 0, but after that I cant draw overlay.plot.
