Dear all, I am trying to write an R function that can estimate Transfer functions *with additive noise* i.e. Y_t = \delta^-1(B)\omega(B)X_{t-b} + N_t where B is the backward shift operator, b is the delay and N_t is a noisy component that can be modelled as an ARMA process. The parameters to both the impulse response function and the ARMA noisy component need to be estimated simultaneously. I

Hi, Does anyone know of a pre-existing function where I can get the t-test confidence interval for a given mean, sd, degrees of freedom and confidence limit. I do NOT want to run any data through the t.test function. Kind regards, Sam. [[alternative HTML version deleted]]

Hi, I have been using R for a few months now and I am confident that the language has everything I will need to complete my PhD. I can create functions, script files and packages, but I would like to write my programs more efficiently (maybe using OO). Can anyone recommend a good book on the "art" of good R programming? Kind Regards, Sam.

Hi, Is it possible to have an array as the output of a custom fact? And then to pass it into a template in Puppet? I currently have a fact that looks like this: Facter.add("exports") do setcode do case Facter.hostname when (/thishost/i): [ "/local", "/local2" ] end end end & a template like this: <%

Hi, I would like to be able to count a sequence of numbers. For example, given a vector of the following integers (1,1,1,2,2,2,2,3,3,3,3,3,3,1,1,1,1, 3,3) the function would return (3, 4, 6, 4,2) Does anyone have any cool ideas to solve this?

Hi, I''m gradually moving my site''s config over to Puppet (still in the testing phases at the moment!). Is there any way of getting/referring to a host''s IP address? I want to set up iptables via Puppet, & can use a template but need to get the IP address into the template somehow. I''m getting my node definitions (& thus classes) from LDAP. I

I'm in the position where I'd like to offer IMAP access to a collection of email accounts which are stored in a very odd manner. Files are stored as: /blah/$dd-$mm-$yy/$domain/1234/1234 For example: /reject/12-3-2009/cvsrepository.org/35199/35199639 There is a single file for each mail, which I guess technically probably counts as an mbox folder, but only just. I

Hi, Is there a function in R that lets one represent an integer in binary format for a given number of bits? So an example would be.... > binary.function(num=5, num.of.bits=8) > "00000101" Or, is this something I have to write myself? Any help would be appreciated. Cheers, Sam.

I''ve been testing Xen for a few weeks now and am just about to put it into production use. (I wrote some scripts to create Debian images easily; the tools are included in Debian Sid as "xen-tools".) The only thing troubling me at the moment is backing up the virtual instances. I''m looking to run about four virtual systems upon a host. If the physical host

I have a coworker, who''s primary expertise is in another flavor of Unix. This coworker lists floating point operations as one of ZFS detriments. I''s not really sure what he means specifically, or where he got this reference from. In an effort to refute what I believe is an error or misunderstanding on his part, I have spent time on Yahoo, Google, the ZFS section of

Hi, I'm using Samba as a PDC with roaming profiles on a Debian Etch machine, the clients are Windows XP/2000 machines. I just installed security upgrades with aptitude, and this upgraded all samba 3.0.24-6etch4 packages to 3.0.24-6etch6 (except for samba-doc which was upgraded to 3.0.24-6etch7). Immediately after the upgrade, my users could not load their profiles at login anymore. Errors
