File permission problem

[johnnyzhz]

Dear Dr. Ooms,

Thank you for providing such a wonderful package. I have been used it for a while. However, after recently updating R, I had some issues. It seemed to be related to file permissions. For example, using the the stock r-user profile, I got the following error:

`

aa_change_profile('r-user')
[1] TRUE
save.image('test.Rdata')
Error in gzfile(file, "wb") : cannot open the connection
In addition: Warning message:
In gzfile(file, "wb") :
cannot open compressed file 'test.RdataTmp', probable reason 'Permission denied'
Warning message:
In file.remove(outfile) :
cannot remove file 'test.RdataTmp', reason 'No such file or directory'
`

Any help on this is highly appreciated! Thanks.
