Hi! how do i get to the source code of kpca or even better predict.kpca(which it tells me doesn't exist but should) ? (And if anyone has too much time: Now if i got that right, the @pcv attribute consists of the principal components, and for kpca, these are defined as projections of some random point x, which was transformed into the other feature space -> f(x), projected onto the actual

2 April 2009 My name is Martin Streicher. I am pleased to announce three new publications dedicated to web developers. Red: The Journal of Ruby Development Facade: The Journal of Front-end Development Tabula: The Journal of Open Source Database Development The three publications obviously have a great number of topics in common between then, and much that is unique. Where ever possible,

Might not be the best place to ask, but i could get lucky.. I have setup an eclipse environment to write sweave files lately and wanted to switch to knitr. I could get it to work on easy files, but my earlier written sweave file fails to be knit properly. Here is the error message: Quitting from lines 273-276: Error in setwd(base.dir) : kann Arbeitsverzeichnis nicht wechseln (it says: cannot

Hi there, I need to do the same thing as cumsum but with the variance and skewness. I have tried to do a loop for like this: var.value <- vector(mode = "numeric", length = length(daily)) for (i in (1:length(daily))) { var.value[i] <- var(daily[1:i]) } But because my dataset is so huge, I run out of memory..... Any ideas?!?! Much appreciate

I am trying to do a power analysis to get the number of replicas per treatment. If I try to get the power it works just fine: setn=c(2,3) sdx=c(1.19,4.35) power.t.test(n = setn, delta = 13.5, sd = sdx, sig.level = 0.05,power = NULL) If I go the other way to obtain the "n" I have problems. sdx=c(1.19,4.35) pow=c(.8,.8) power.t.test(n = NULL, delta = 13.5, sd = sdx, sig.level = 0.05,

Hello R-Help! I've looked around and have not found: A simple(short) way to hide functions and variables from the global environment. What i want is for a few of them to only be accessable from the scriptfile they're in. I probably could do fun things with environments , but that seems quite a hassle. As example: I have a file that gets me stuff from the database and creates an R object

Can i somehow append objects to an .Rdata file? I didn't see an option for it in the save() method. dump() won't work since i have s4 objects in there.

Hi! If i found a problem with the code of one of the libraries (not core), or, in my current case, would wish something minor changed for convenience, where can i get contact? Can i put it in the "official" bug repository? (Problem discription for anyone interested: Why call the default function kpca for a matrix with kpar=list(sigma=0.2), instead of putting this default sigma into the

I have to persist some data in the database to test the interactions between two of my models. One model has a serial number attribute that is unique, so it must be entered once and only once. rake spec deletes all the data, allowing my tests to pass. . Running rspec under TextMate produces a fail, however, because the data in tables remain. This is somewhat inconsistent, too. Running it

My server just literally was brought to it's knees with this message spewing on the console: swap_pager: indefinite wait buffer: bufobj: 0, blkno: 1203133, size: 4096 (blkno and size were varying) Some searching says that this is or was a bug.

Thanks Bill.

Following problem: Say you have a bunch of parameters and want to produce results for all combinations of those: height<-c("high","low") width<-c("slim","wide") then what i used to do was something like this: l<-list() for(h in height){ l[[h]]<-list() for(w in width){ l[[h]][[w]] <- doSomething() } } Now those parameters aren't

Hello, At guides.rubyonrails.org I read about the possibilities of find_in_batches. However I cannot find this option anywhere in the API documentation (api.rubyonrails.org). My question: where should I look for the documentation of this command? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This change allows use of untrusted X11 forwarding (which is more secure) without requiring users to choose a finite timeout after which to refuse new connections. This matches the semantics of the X11 security extension itself, which also treat a validity timeout of 0 on an authentication cookie as indefinite.

What are some effective ways to leverage the strengths of R and Mathematica for the analysis of a single data set? More specifically, are there any functions that can assist with any of the following? 1. Calling an R function from Mathematica. 2. Calling a Mathematica function from R. 3. Using XML or another reliable data format to pass vectors, matrices, and/or lists from one environment to

Has anyone built ruby-debug for Ruby 1.9.1? I am on Leopard. A check around the Web yielded issues with the pair, but no solution (I''ll keep looking), hence my question. Martin

Hi All, I need to normalize/scale string variable which represents interests of customers (e.g., 'cycling, rollerblading, swimming' etc).

I'm not sure what the parameter specifies: random if an integer value is specified, random parameter vectors are drawn from the parameter space. What are the parameter vectors and what is the parameter space? What means drawn? greetings Jessi [[alternative HTML version deleted]]
