I have written a R script for extracting GEO files form NCBI GEO using GEOquery and analyze the data. Now I want to extract multiple files using multiple GEO IDs and run the script on them one by one so that I can get separate files for different IDs. In short, I want to know how can we download multiple files using GEOquery and how to use loop for analyzing all those files? Please tell me. Thanks in advance.
