Esteemed R users and developers, How does one 'programatically' list or call objects for use in a function? For example, i thought i could do something better than this: save(A.cwb, B.cwb, C.cwb, D.cwb, E.cwb, F.cwb, file="afile.RData") with something like these- prfxs <- c("A", "B", "C", "D", &q...

Now I can easily determine wether I''m running on a modified kernel or not (by checking for the presence of /proc/xen). However, once I''ve found

Hi, I need to construct a formula programaticly, and pass it to a function such as the linear mixed model lme. The help says it requires "a two-sided linear formula object describing the fixed-effects part of the model" but I do not know how to create this formula. I have tried various things using formula(x, ...), as.formula(o...

I need a way to kill the ferret_server drb process programatically, so I can start/stop it as part of the capistrano deployment process. This should be as simple as adding some sort of stop method to ActsAsFerret::Remote::Server. I was just messing around and was able to do it by modifying method_missing to look for the :stop method and then calling DRb.thre...

Hi, new to the list, R and rpy. my first post. using rpy, i find this r.X11(height=3, width=6) allows me to preset the size of a subsequent r.plot(x, y) but i've been unable to find documention on related aspects, such as programatic control of the plot window location on the monitor, or programatic resizing of a plot once it is generated. Are these possible? In general I've found it diffcult to use google to search for answers because "R" is not a very effective keyword. Are there tricks to googling for R info?...

Thanks for your answers... But IMHO it''s hacky and error-prone to rely on the name of the host to determine if it''s a domU or a dom0 (or an unmodified kernel) :( I don''t like that much neither changing the name of the kernel :-/ I need to be able to determine, as a normal user (that is: non-root), if I''m running in a domU or not (I can already tell if

Hi all, I have been lurking here on and off for a while and have recently returned after being off-list for a few months, I've searched the MARC list archives and can't see any useful information for my situation. Basically, I have a system that calls out to the samba command line utilities pdbedit/smbpasswd etc to modify user account information. This is okay, but very slow and

Is there an easy way to programatically work out the associations on a model? If not, is there a positive reason it was omitted, or is it just something that hasn''t been implemented yet? Thanks Gareth

Has anyone considered making a linkable library of the OpenSSH code so that one could programatically interact with ssh? Or is there some other method to accomplish this? Thanks, -Eric

The XML package relies on libxml2.dll (e.g., bundled with the CRAN binary) installed in library/XML/libs. Unfortunately, c:/WINDOWS/system32/libxml2.dll will be found and loaded before this. Is there any programatic solution? Thanks, Martin -- Martin Morgan Computational Biology / Fred Hutchinson Cancer Research Center 1100 Fairview Ave. N.

Hi, On ocasion, you need to subscript an array that has an arbitrary (ie. not known in advance) number of dimensions. How do you deal with these situations? It appears that it is not possible use a list as an index, for instance this fails: > x <- array(NA, c(2,2,2)) > x[list(TRUE,TRUE,2)] Error in x[list(TRUE, TRUE, 2)] : invalid subscript type 'list' The only way I know is

Hello again, Let say I have following vector: set.seed(1) Vec <- sample(LETTERS[1:5], 10, replace = TRUE) Vec Now with each repeated letter, I like to add suffix programatically. Therefore I want to get following vector: c("B", "B1", "C", "E", "B2", "E1", "E2", "D", "D1", "A") Can somebody tell me how to achieve that? Thanks and regards,

...o put GPL text and a copyright notice at the start of each source file. For the .rb files, this will look like: # Copyright 2006 Robert Jones........... and for the .rhtml files it will look like: <!-- Copyright 2006 Robert Jones......... Can anyone think of a neat way to do this prepending programatically on Linux, rather than by hand? I''m sure I can be done with awk, sed, grep etc. Thanks in advance, -- Robert Jones

Why is RJS so dependant on programatic creation of Javascript? RHTML is a great implementation in that it puts HTML first, and Ruby second. I would have thought RJS would be the same way: a .js with ERb helpers for generating Javascript functions. RJS putting Javascript second means: - I have to learn a whole new set of commands to...

Hi, is it possible to access xenstore through libvirt? Or at least any other programatic means other than calling xenstore-read/write through shell? I understand it is somewhat of a security risk but still... Thanks, Marin

I am looking for a way to programatically modify DNS settings from outside of my SAMBA4 DCs. I am working on creating a PHP inventory page, which (in an ideal world) would hook into our SAMBA4 domain controllers, allowing us to modify DNS records in the inventory, and then have the backend of the inventory communicate with the DCs ove...

...isk will have three partitions: [BOOT: (FAT16 w/ SYSLINUX)] [OS1] [OS2] OS1 and OS2 will both contain an XP Embedded system which is read-only and which will always boot from a hibernate file. What I'd like to be able to do if flip-flop between them at runtime (that is, run from OS1 and then programatically select the OS to boot into on the next boot). The catch is, in order to use the XPe hibernate-one-resume-many feature, both of these systems are read only so I just can't go and tweak the boot.ini file. I was looking at the chain boot capabilities of syslinux, but I haven't had luck ge...

...t this way is bad, just that I''m very green :) Question Two: I actually have a bunch of attributes that need to be protected. Rather than hand-writing a call to the ''it'' method for each attribute, could I just loop over an array of attributes that need to be checked and programatically define the ''it'' calls? Pseudo-code: describe Order do [:total, :id, :customer_ip, :status, :error_message, :updated_at, :created_at, :finalize, :tax, :shipping].each do |attribute| it "should protect #{attribute} attributes from mass assignment" do @ord...
