... Unfortunately, I don't have that functionality implemented. You can download the series matrix files by hand and then read them using `getGEO`, though. I will not be able to get to it soon, but if you want, feel free to file an issue to add reviewer link functionality (https://www.ncbi.nlm.nih.gov ...
