Hi, In limma there is this plot function: plotMA3by2 It's great. But it doesn't seem to allow me to assign a file name. And it ignores any jpeg or other device calls before it where i could assign a filename. It is writing to the current directory, which I have no write privelege to. So any idea how I can assign a filename? Thanks, g -- Systems Programmer Yale Center for Medical Informatics fax: 203-737-5708

The plotMA3by2() function is quite simple, so it would be relatively simple to modify it to do whatever you like, including adding an argument that directs where to save the file. Try typing plotMA3by2 at an R prompt to see the function. Best, Jim > > Thanks, > g > -- James W. MacDonald Affymetrix and cDNA Microarray Core University of Michigan Cancer Center 1500 E.
