Dear List,
I want to get all the Affymetrix datasets (Human) from GEO and then
group them according to different types of chips, like hgu133A,
hgu133plus2, etc. so that I could know how many datasets available for
each type of chips.
I looked at the GEOquery package in R/Bioconductor. There are a
'manufacturer' and a 'Title' field in the GEO Platform record which
might be useful for my purpose, but I didn't manage to figure out how
to get all the Platform records into R workspace first. In the package
vignette, it always deals with a single record by giving a specific
accession number such as GPLxxxx, but how could I get all the records
meet my criteria? Could you kindly provide some help on this? Thank
you very much in advance!
kind regards,
Yuan
