Hi,

How to do a GEO query using keywords in R?

I found a few publications but they use the GSE accession number:

GEO_DATASETS <- c("GSE73835")

eset <- getGEOdataObjects(GEO_DATASETS[1])

eset

Thanks a lot.

D.

What exactly are you asking? You say something about keywords, but then you try to use a GSE ID, using a non-existent function.

I don't know if it's possible instead of using GSE accession numbers to use keywords like c("arabidopsis", "drought") and get all the related GSE accesion numbers. Is there any way to do that?

You could either use the Bioconductor GEOmetadb package, a web interface query on the NCBI website, or eUtils. There are other third-party options as well as similar functionality at EBI.

Just guessing that this is what you want:

library(GEOquery)
eset = getGEO('GSE73835')[[1]]
eset
