You might want to read 'An Introduction to R', which outlines simple manipulations such as this.

Dear Sir/Madam:
     Glad to writing to you.
     I'm trying to use limma to analyse my microarray data. now I can get the "MA.txt"file which contains all of the ratios and intensities. but I want to get those genes that differentially expressed, ie. the log ratio is <-1 or >1. Could you write a command to write those genes to a seperate file.
     thanks, and waiting for your reply.
 your sincerely
                                       Gang Wei
