I have .zip and .7zip files (.csv) that are encrypted that I want to read in R without unzipping the data. I know I can open such files if they are not encrypted without unzipping them first, R Reading in a zip data file without unzipping it, but in this case the files are encrypted. Do you know how I can decrypt them and load them into R without unzipping them?
It should be said that I only need a solution for one of the file formats if there is only a solution for one of them.
