Password-protect R script files
...OS
based folder protection route, however making available such a method in
the open forum would only kill the very spirit of R.
But if someone is able to convince me the genuineness of his reasons to
achieve such a purpose, I might decide to provide selective service to
achieve the same.

@Don your solution does not solve Vijayan's scenario 2. I used spread and

An alternative solution to insert mising Fval - picking up with Don's

kupdate daemon
Hi,
I'm using linux 2.4.25 and I'm trying to change the wakeup interval of
kupdate daemon. Is there a way to change that ?
I once used 'update' tool for that. But that is not there in 2.4.25.
Has it been removed ?
I appreciate any help regarding this.

Journal file location
...file system, I'd like to use an
inode at a different cylinder group and some other set of blocks. Even if
I'm allowed only to use one of the reserved inodes, is it possible to put
the journal file somewhere in the "middle" of the file system rather than
at the beginning ?
Thanks,

fsync in ext3: A question
...t file is in 'data=journal' mode, would the fsync() return once the
data gets safely into the journal ?
On the other hand, if that file is in 'data=writeback' mode, would the
fsync() return only when the data gets safely into its actual location ?
Any help is appreciated.
Thanks,

Transaction semantics in ext3
Hi,
I have a doubt on how the transaction semantics work in ext3.
When I copy a file, does the entire copy is treated as one
transaction so that finally I have either the full file or
no file. Or will it be split into multiple transactions which
can result in copying partial files.
thanks,

...from x and y
how can i modify the htest argument in the above function to permit
running chi-square on each strata?
I know add.chi.squared() will help, but if i want to use the
add.cross.strata.test, then what change in chi-squared function should i
carry out to overcome this error?
