[BioC] limma toptable output

[Dick Beyer]

In the limma manual, 27 October 2003, near the bottom of page 3, the output from the command 

topTable(fit, n=30, adjust="fdr")

shows a column "A".  

Block Row Column ID Name M A t P.Value B
3721 8 2 1 control BMP2 -2.21 12.1 -21.1 0.000357 7.96
1609 4 2 1 control BMP2 -2.30 13.1 -20.3 0.000357 7.78

However, the help for toptable specifies "A" as an input parameter.

How did the "A" column appear in the output when it was not specified as an input argument?

Thanks much,
Dick
