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 everyone I have banking data set in long format with 4 columns.One of these columns is bank name which consist of 49 banks and I want the data for only 40 banks out of these 49 so can anyone help me on how to get this 40 banks data My data looks like Year Name totalliabilties assets 1990 a 90 10 1991 a 89 48 1992 a 87

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

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

Hi All, I need to normalize/scale string variable which represents interests of customers (e.g., 'cycling, rollerblading, swimming' etc). Does anybody know how to do this, I want then use it along with other numeric variables for SVM classification. Appreciate for any advice. -Alex [[alternative HTML version deleted]]

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]]

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

Hi! I am getting a lot of numbers in the background of the pca screeplots if i use call("plot") and eval(somecall). Til now, creating the calls and plotting later on this way worked fine. Example: pcaI<-prcomp(iris[,1:4]) plot(pcaI) x<-call("plot",pcaI) eval(x) Anyone got an idea how i can avoid that? (also it might take a second or so for the numbers to appear,

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

I'm making tables for prediction results of classifiers (2 classes) that show the usual numbers, true positives, false positives, etc I used the command table(predictedLabels,realLabels) to make those. I just had a case though ,where one of the label vectors had only one class in it. This will result in only half a table. Compare: x<-c(1,1,1,0,0) y<-c(1,1,1,0,1) table(x,y) to

Everyone, I'm very new to R, especially when it comes to loops and functions, so please bear with me if this is an elementary question. I cannot seem to figure out how to construct a loop which runs a function until a certain value is computed. For example, say I have the following: num = numeric (10) num [1] = 0 for (i in 2:10) { num [i] = num [i-1] + 5 } This adds 5 to the

Hi, I have been using ffsave.image() to save mixture of ff and normal objects in my workspace. e.g. ffsave.image(file = "C:\output\saveobjects", rootpath = "D:\fftempdir", safe = TRUE) It works fine but once my workspace has large (~4GB) objects, I get the error: Error in ffsave.image(file = "C:\output\savedobjects", rootpath = "D:\fftempdir", safe =

I had a problem much like the one that Matthias Koeppe experienced. I would only get the BUS error when running in a YASSP-modified system, though. The binary worked fine on a non-YASSP host. I applied his change to use a long for the mask, and it works now. Cheers, -Thomas __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search

The following patch appears to fix the BUS error received on Solaris 8. This problem manifests as an immediate disconnect with no apparent cause immediately after authentication with the host. --- Darren Tucker <dtucker at zip.com.au> wrote: > Date: Tue, 30 Sep 2003 09:35:26 +1000 > From: Darren Tucker <dtucker at zip.com.au> > Subject: Re: Bus Error with OpenSSH 3.7.1p2 on

Hi, I know that with readlines you can start executing a code upon user input. What I would like to do is to have the ability to abort a code based on a new user input. E.g. when the user hits enter the code stops running. That is, I would periodically check for a user input and stop the code when the correct input was entered. Below is an example of a function which would run an endless loop

I built OpenSSH as a 64-bit binary on Solaris 9, using gcc 3.3.2, OpenSSL 0.9.7c and zlib 1.2.1. sshd starts up normally, and will begin the login session, however, some time after it reads /etc/default/login, it faults and kills the connection. There are no error messages logged to syslog (with LogLevel set to DEBUG) or with the -ddd option. Here's a truss of the failure: 8132:

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,

The story of this problem, AFAIK, is that Solaris 8 YASSP and JASS and vigilant/paranoid sysadmins have been known to set a restricitve umask in /etc/default/login. OpenSSH compatibility for Solaris 8 has been spotty at times for sparcv9 targets. This time, when a sparcv9 binary tries to sscanf(3C) the numeric umask as a long octal and put it in a mode_t, SIGBUS happens. What this looks like in

Hi, the function outer can not apply a constant function as in the last line of the following example: > xg <- 1:4 > yg <- 1:4 > fxyg <- outer(xg, yg, function(x,y) x*y) > fconstg <- outer(xg, yg, function(x,y) 1.0) Error in outer(xg, yg, function(x, y) 1) : dims [product 16] do not match the length of object [1] Of course there are simpler ways to construct a constant
