Hello All! I''m novice at ROR. Would you like to explain what mean such constuction in Ruby. 1: class DemoController < ActionController::Base 2: scaffold :item 3: end Is 2th line calling of method ''scaffold''? If it is so, when it called? For all instances of class, or only for class? I watch sources of ActionController, but don''t understand completely.

As far as I can tell, when you construct a type using the support library StructType::get, you have to pass in a list of types. How can you make a Recursive type by passing in a pointer to the type you are constucting. An example where something really simple like the line below was output would be perfect. %struct.linked_list = type { %struct.linked_list*, %sbyte* } Thanks for any help,

Hi, First, thanks to those who helped me see my gross misunderstanding of randomForest. I worked through a baging tutorial and now understand the "many tree" approach. However, it is not what I want to do! My bagged errors are accpetable but I need to use the actual tree and need a single tree application. I am using rpart for a classification tree but am interested in a more unbaised

Hello, I'm trying to script an installation and can't find the command-line argument to "samba-tool domain provision" to specify the DNS forwarder. I have tried "samba-tool domain provision --help" but I couldn't see such an option there. Does that mean there isn't one ? I also tried to use the "samba-tool --option=option" construct (described on

Dear Listers, I am having trouble figuring out how to build a formula using a variable list. For example, I have: a _ data.frame(a=rnorm(1000)) a$b_rnorm(1000)+.5*a$a a$c_rnorm(1000)+.5*a$b a$d_rnorm(1000)+.5*a$b+.1*a$a attach(a) and I estimate, lm(d ~ b+c+d) BUT, I wish to construct a generalized solution in which, ListOfVar _ c('b','c','d') The question is how

I am using an algorigm to split my data set into two random sections repeatedly and constuct a model using rpart() on one, test on the other and average out the results. One of my variables is a factor(crop) where each crop type has a code. Some crop types occur infrequently or singly. when the data set is randomly split, it may be that the first data set has a crop type which is not present in

Dear List-Members, since 3 weeks I have been heavily working on reproducing the results of an economic paper. The method there uses the numerical solution of an integral within nonlinear least squares. Within the integrand there is also some parameter to estimate. Is that in the end possible to implement in R [Originally it was done in GAUSS]? I'm nearly into giving up. I constucted an

Hi Yawl, After about 6 months of prattting about I've convinced my boss that we should be installing * into our currently under constuction Data Center in Somerset NJ. There will be 10 permanent people and DR space for another 50. My plan is as follows; ATAComm dual XEON server with quad T1 board. A handfull of ATA's for fax machines, job lot of X-Pro softphones for the DR bit, Polycom

Hello, I've noticed that SPLUS seems to have a function for evaluating derivative matrices of splines. I've found the R function that evaluates matrices from 'smooth.spline'; maybe someone has written something to do the same with smooth.basis? regards, s

Thanks for you reply. In our case, we want to get a weight using the user' properties(age, gender, price preference) and products' properties(price, comment count, purchased amount among different gender or range of age). So our weight function is complex, no matter we use KeyMaker or PostingSource, six to eight values in slot will be used. But we find that using doc.get_value(slot)

This is just a curiosity question. Why do the two different syntaxes for df1 and df2 give such different results in the names(dfx)? Thanks df1 <- data.frame(nas = c("A", "B" , "B" ,"C" ,"B", "A", "D"),nums = c(3, 2, 1, 1, 2, 3, 7)) df2 <- data.frame(nas <- c("A", "B" ,

Hi, I am attempting to connect my dell SC420 to a 32" LCD at 1366x768. I have attached my currect config file and currect X start log. How do I massage the xorf file to run at the native resolution of the LCD? It currently runs but is in a virtual mode. The screen scrolls. Any help is appreciated. I am using Centos 4.1.

Suppose I have a string of objects names: name <- c("foo", "bar", "baz") and I would like to use a for loop to automatically create three objects called "foo", "bar" and "baz" accordingly. Then how can this be done" (so that in the workspace, foo = 1, bar = 2 and baz=3) for (i in name) { ..... } Thanks! Mark

Hi all, I am using R1.5.0 under Unix, I have a couple of questions here. 1. My program is running out of memory. I am writing a program to grow a list of trees using rpart() on a subset of a large dataset(5807x693) with a different response for every tree. I saw that after each tree was constucted, 116 MB of data was being added to the Vcells. I have no idea what this data is. My dataset is

I did mean domU instead of dom0. :-) The point here is that time_resume will sync to new system time and wall clock at restore, and thus pv guest should be able to continue... Xen system time is not wallclock time which just counts up from power up. As Keir points out, only its
