To explore the expression of the genes, the package provides a submenu IsoPlot from Plots menu. This feature displays the data points, sample means at each dose and an isotonic regression line.
Plots > IsoPlot
User need to input gene name(s) or row number(s) or using a range of row numbers (max 9 genes).
Other options:
a. Dose as ordinal. This option will draw the plot and treat dose as ordinal scale. The default will plot with dose as a continuous variable.
b. Show isotonic regression curve for both direction. The default plot just display the isotonic trend/curve which is more likely fit the data.
By checking this option, the isotonic trend for both directions will be displayed.
c. Show summary of the data. This option is to provide a short summary of each selected gene.
