When you use RStudio through the AMI, you are logging in as the
"ubuntu" user. For security reasons, RStudio does not allow you to log
in as root.

So the solution is to make sure the directory where you want to save
data is writeable by the ubuntu user, or, after you've saved your data
in ubuntu's home directory, ssh in as root and move it to where you
want it to go.
