... The GEO Series Matrix files are a reflection of what is submitted. Unfortunately, the submitters did not submit any normalized values. Instead, they submitted only the .CEL files, it appears. So, you are stuck with needing to download the .CEL files and processing those as raw data. That isn't n ...

... Thanks, Val. row.names=FALSE is a good solution for our use case. If unique IDs are of interest, hashing approaches would be potentially interesting to folks, but perhaps that is best left as a user-level decision. Part of my rationale for asking was to see what others thought.

... With some newer VCF files, particularly those that have come from structural variant callers, the rownames of the resulting `VCF` objects (when the ID column is missing) can become problematic or excessively large. To give a concrete example, we have VCFs with insertions of dozens or hundreds of bas ...

... The objectStoreR package is VERY specific in that it only deals with CSV files. As a simple starting place, you could contact the author and ask if he/she is willing to write a objectstore.fetchToDisk() function that simply grabs an object and writes it to disk. That would allow you to interface wi ...

... I noticed a numeric difference between the AD geno field when going from a CollapsedVCF to ExpandedVCF. Here is an example. I can share the VCF offline, as it is human data. In the example, it seems that after expansion, the AD numbers appear to not match the CollapsedVCF version.

... An upgrade to GEOquery 2.40 will likely fix the problem. NCBI has moved away from using "http" in favor of "https", so you'll need to update GEOquery to address that issue. Sorry for the inconvenience!
