My employer historically used R:BASE to store important information, but we no longer have access to the program and the data are sitting unused. It's four files (survey.rx1, survey.rx2, survey.rx3, and survey.rx4) that together form a relational database. I believe these are binary data from searching for information on the program and ".rx" extension.
I would like to convert these data into a format that is usable in R or Excel (.csv, .xls, .xlsx, .RDS, etc.), but the free trial version of R:BASE does not allow exports and trying to import the data into MS Excel isn't working (using the get data, from file, from folder feature. It recognizes it as binary and shows some metadata but doesn't display the actual content).
Trying to read these data in R I explored using readBin, but am struggling to determine an appropriate value for "what" as the columns represent different modes and I don't have a connection object to provide that information. I explored using RevoScaleR which looked like it could be relevant but the Documentation says it was built on R 3.5.2 and the Machine Learning Server you need to run it is no longer being supported as of this year.
So, if anyone knows how to convert these data or knows of a free alternative to R:BASE that works for these data types I would be very appreciative. Thank you!
