MAplot: MAplotHelpfile

In tRanslatome: Comparison between multiple levels of gene expression

Description

The MA plot displays the average log2 signal of the genes on the x-axis and the log2 fold changes on the y-axis. The upper plot represents a MA plot for the first level of gene expression analysis, whereas the other one refers to the second level. DEGs are color labeled. This function takes as input an object of class DEGs.

Usage

MAplot(object, outputformat="on screen",track="")

Arguments

object	an object of class DEGs.
outputformat	a character string specifying if the plot is saved in jpeg (jpeg), postscript (postscript), pdf (pdf) format, or it is simply displayed on the screen(on screen). By default this value is on screen.
track	a character vector of gene names that will be explicitly highlighted in the scatterplot, if they match any gene contained in the object of class DEGs. By default this vector is empty.
