ArrayExpress allows to submit raw and processed data. The latter is "a two-dimensional spreadsheet files in tab-delimited text (.txt) format" .
Question: has anyone a minimalistic snippet of R, exemplifying how to produce/export such preprocessed data, something similar to:
library(simpleaffy) library(ath1121501.db) abatch <- read.affy(path=..., covdesc=...) eset <- rma(abatch) data <- exprs(eset) write.delim(data, file="
In particular, I'd be interested what are recommended formatoptions, such that gene annotation etc. will not break import into other software (quoting ? row/column names ?). Bonus points if this can be read directly back with package ArrayExpress  via
Thanks in advance,
