dear all,

i am very new to Bioconductor,

now i am planning to do data analysis based on "GSE22216"

i succeeded in download that data, but on the next step, i would like to handle this GSE22216 data to

eppr Set object.

because finallly i would like to welch t test using mt.maxT procedure.

would you mind telling how to handle GSE22216 to exprSet object ?

thanks in advance

Something like this should work:

## load the GEOquery library
library(GEOquery)
## download the dataset of interest
dat <- getGEO("GSE22216")
## dat is a list, so lets get the first entry, which is an ExpressionSet
dat2 <- dat[[1]]
is(dat2)
