[BioC] how to get normalized counts from edgeR

[wang peter]

dear all:
 i have two questions

1. is the "size factor" from DESeq equally to the "norm factor" in the edgeR

2. i can get the normalized counts by

counts(obj,normalized=T)

how to get normalized counts from edgeR
can i use the each col of count matrix divided by norm factor
