[BioC] How to save the RMA result in .RData file (oligo package)?

I currrently use the following code to generate RMA results (in
exprs.txt). But it is inconvenient to save a text file. If I can save
the result in '.RData' format, it would be faster.  I'm wondering what
variable in 'eset' I should 'save()' into '.RData' format.

library(oligo)
cel_files = list.celfiles('.', full.names=T,recursive=T)
data=read.celfiles(cel_files)
eset=rma(data)
write.exprs(eset, file="exprs.txt", sep="\t")
