Write MA-Plots to Files


Write MA-plots to files in PNG format, six plots to a file in a 3 by 2 grid arrangement.


plotMA3by2(MA, prefix="MA", path=NULL, main=colnames(MA), zero.weights=FALSE, common.lim=TRUE, ...)


MA an MAList or RGList object, or any list with components M containing log-ratios and A containing average intensities
prefix character string giving prefix to attach to file names
path character string specifying directory for output files
main character vector giving titles for plots
zero.weights logical, should points with non-positive weights be plotted
common.lim logical, should all plots on a page use the same axis limits
... any other arguments are passed to plotMA


This function writes a series of PNG format files to disk. Each file contains six MA-plots in three rows and two columns. The layout is optimized for A4-sized paper.


No value is returned, but one or more files are written to the working directory. The number of files is determined by the number of columns of MA.
