Please read the comments in the help about umask (and in the posting
guide about the 'at a minimum' information required in postings, for
the details do depend on the version of R and it seems yours is not
current).
In R 2.13.0:
‘dir.create’ creates the last element of the path, unless
‘recursive = TRUE’. Trailing path separators are discarded. The
mode will be modified by the ‘umask’ setting in the same way as
for the system function ‘mkdir’.
so try
um <- Sys.umask(0)
dir.create('test/sub', recursive=TRUE)
Sys.umask(um)
(Whether mkdir -p respects umask depends on your OS ... and the
command-line command and the system call of that name may differ.)

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
