Quick newb question about R relating to the line of code below: rawCool = read.zoo("cooling.txt", FUN = as.chron, format = "%m/%d/%Y %H:%M", sep = "\t", aggregate = function(x) tail(x, 1)) I'm wondering what the specifics are for the argument where it has "aggregate = function(x) tail(x, 1)". I understand that it removes the last row of

This is a newb question, and probably one that is a matter of taste more than objective merit. I''m working on a home server, running Linux [FC 4], hosting a website [look for generocities.com shortly]. I have a delightful new Windows XP Pro Dell Inspiron 9300 laptop. What would the community recommend for the environment in which I develop? I don''t mean technologies like RoR

I think im using Gnome but im not sure. As for using logout command it didn't work that's why I got puzzled and had to ask online since I couldn't find the GUI one which was there but apparently im too blind to see. Speaking of GUI side of things that's why I made the comment about no search features in CentOS. None of my menus offer a search feature in the GUI so I would have to

If you really want to do this the asterisk list is based off of mailman. You can learn all about mailman here: http://list.org/ But really, what are the odds that newbs will know to go there first? Are you going to moderate it? Someone has to actually answer the questions you know, if a newb only list is going to exist. Look, don't answer lame questions if you don't want to. Flaming a

I have a template that belongs to a certain model (model A). I need to call a helper method of a different model (model B). Then I need the helper method of B to call a helper method of model C. I tried using "include" and "require" and using namespaces, but I got "undefined method". What is the way to do it? -- Posted via http://www.ruby-forum.com/.

This is probably pretty easy, but I''m still a newb as far as ruby and rails goes.

I'm trying to load a dataset into R, but I'm completely lost. This is probably due mostly to the fact that I'm a complete R newb, but it's got me stuck in a research project. I've tried just opening the text file in WordPad and copying the data directly into R, but it's too big and causes the program to crash. Any suggestions or assistance? I'm kinda desperate and

Hey all, Ok this is probably a newb question, but I haven''t been programming with MVC for very long, and I''ve been wondering what the general opinion is, or best practices, for making a new controller. Like what cases would you need a new controller for and what cases can you just put everything into one controller? Thanks in advance, Randal -- Posted via

I couldn't help but take notice at some of the responses that were coming in from when I was posting questions due to my ignorance of Linux. Some people were quick to help, some advanced users I am sure ignored me because im not worth their time, and then some other users tried to help but was unable to dumb their speech down to newb levels. However I am thankful that there is people here to

Maybe this marks me as a real newb but where do I set the number of rings that a phone has before it sends it to voicemail? Also for some odd reason when I ring an extension attached to my sipura 2100 ATA it takes it about 12 seconds to start ringing after I dial it (sits there with dead air on the calling phone). Any idea on these, am I missing some simple configuration switch for either?

Im sorry if this is a newb question, but how do you recompile the kernel in CentOS 4.3? I need to add reiserfs support (even though the setup detected it) the kernel it gave me didnt have support for reiserfs, and my entire fileserver is all reiserfs. I tried the gentoo way, which im use to and it bombed. What do i need to do? does it install kernel source by default? I couldnt find any good

Sorry to be a newb about this, but I''m trying to integrate rcov into my tests. I tried to follow the example located here: http://rspec.rubyforge.org/tools/rcov.html But to my dismay, I just don''t understand what to do.
