Comment: C: How to check the read length for all the TCGA data samples in GDC?
... Sure. library(dplyr) rg_info = bind_rows(z$analysis$metadata$read_groups) You may need to play with things a bit to get exactly what you want. The str() function can be quite useful, as are things like class() to see how things are stored in these complex structures. ...

Comment: C: Need help loading gene expression data into R using either ArrayExpress or GEOqu
... You'll need to update R and GEOquery. That SSL error is due to a change at NCBI that has been addressed in recent GEOquery versions. As for ArrayExpress, there is no "processed" data, so that approach won't work. See my answer below. ...

Answer: A: Need help loading gene expression data into R using either ArrayExpress or GEOqu
... You'll need to download the supplementary files from GEO and then determine the best approach to process them. You can use the getGEOSuppFiles() function to download those raw data files. The phenoData from a getGEO() call can still be useful, though, for building out the sample information.  ...
