The cause of “bad magic number” error when loading a workspace and how to avoid it?

Question

I tried to load my R workspace and received this error:

Error: bad restore file magic number (file may be corrupted) -- no data loaded
In addition: Warning m         


        

Answer 1

I had this problem when I saved the Rdata file in an older version of R and then I tried to open in a new one. I solved by updating my R version to the newest.
