Linux systems have a user mask that limits the file mode creation
possibilities of any processes launched from that shell. If you check
your /etc/profile file, you will see the line
umask 022
This prevents you by default from creating files with write access for
everyone except the user. In other words, this is a linux issue, not an
R issue -- the same thing happens when you use mkdir. This can be
overridden, however. For example,
system("chmod -R 0777 test")
which recursively changes the mode of test and all its subdirectories
from within R.

Dear list,
I am trying to create a folder structure, say 'test/sub', and set the
folder and sub folder to be writable to everyone.
By default
dir.create('test/sub', recursive=TRUE, mode='0777')
creates folders with mode: drwxr-xr-x
After
Sys.chmod('test/sub',mode='0777')
The folder 'test' is: drwxr-xr-x
and the sub folder 'sub' is: drwxrwxrwx
The question is how to generate a folder and sub folders, with every
folder being drwxrwxrwx ?
I am using a linux/redhat system.
Thank you for your help.
Xian
