The first group, comprising GDS, GPL and GSM, all have. 22 Oct 2015 In order to explore and download GEO data from whitin R, we can use the following libraries: Now that i have a GEO Series Id, I am using GEOquery to download the corresponding files. gse <- getGEO(myGSE) Briefly, gse includes data about GEO datasets, gsm includes data about individual GEO 5 Aug 2016 First, let's start by opening an R session and creating a function to return the eset Make sure the GEOquery package is installed. require ( "GEOquery" ). # Use the getGEO() function to download the GEO data for the id stored in x. GSEDATA We will first need to download the annotation file for GPL6887. The soft files and matrix files from GEO contain metadata and abundance data about the experiment. I downloaded te soft data and loaded directly on R using the comands on Neil Graham link: gds858 <- getGEO(filename='GDS858.soft.gz') https://www.bioconductor.org/packages/devel/bioc/vignettes/GEOquery/inst/
