I used R-studio to merge WoS and scopus data. Everything was fine and the merged file was handly to use. Then, because of a reason there was a need to change my laptop. Now, I have a new laptop with almost all data recovered and trying to use the same command to merge WoS and scopus data but getting the error message.
Code entered: web_data<-convert2df(".txt")
Error message: Error in file(con, "r") : cannot open the connection
