Colleagues, I am in the process of learning R. I've been able to import my dataset (from Stata) and do some simple coding. I have now come to coding situation that requires some assistance. This is some code in SPSS that I would like to be able to execute in R: if (race eq 1 and usborn=0) confused=1 . if (race eq 2 and usborn=0) confused=1 . if (race eq 1 and usborn=1) confused=0 . if (race

For a private package ("soon" to be on CRAN), I started looking at and thinking about the function confusion() from the mda package and wondered if it wouldn't make sense to provide the generic function in base R and also think about making the default for the `true' argument equal to fitted(object). One could write methods for confusion() for almost all classifiers which

Hi, I am trying to print out my confusion matrix after having created my random forest. I have put in this command: fit<-randomForest(MMS_ENABLED_HANDSET~.,data=dat,ntree=500,mtry=14, na.action=na.omit,confusion=TRUE) but I can't get it to give me the confusion matrix, anyone know how this works?

I have a question on the output generated by randomForest in classification mode, specifically, the confusion matrix. The confusion matrix lists the various classes and how the forest classified each one, plus the classification error. Are these numbers essentially averages over all the trees in the forest? If so, is there a way I can get the standard deviation values out of the randomForest,

hi I try to understand the code of balloon ,and got confused about the following parts of code: static int decrease_reservation(unsigned long nr_pages) { .... if (!PageHighMem(page)) { v = phys_to_virt(pfn << PAGE_SHIFT); scrub_pages(v, 1); ret = HYPERVISOR_update_va_mapping( (unsigned long)v, __pte_ma(0), 0);

Hello everybody, I am somewhat confused by the following method within the LLVM, especially the lines "confusion starts" -> "confusion ends" are hard to follow. Maybe the idea is that if there are such big data structures one does not waste much memory anyway if they are aligned to a 16-byte boundary. However, my assembler complains here because it only supports 1-, 2-,

Hello, this morning my centos 5 server (2.6.18-53.1.4.el5) failed on the dvd device and disabled dma. The dvd-writer (/dev/hdg) is connected to the following controller as a secondary master. 02:07.0 RAID bus controller: Silicon Image, Inc. PCI0680 Ultra ATA-133 Host Controller (rev 02) There is also an harddisc as primary master connected on this controller. This harddisc is the only device in

I ran into this exact issue last night - http://www.iotti.biz/?p=433 When a computer is connected via IPv4 but the IPv4 a repo host connects to is not available, yum then tries the IPv6 address and will fail with a confusing message telling you it failed to connect to the IPv6 address. I don't know if there is a way for yum to figure out whether the current network connection to the

Hi All, Okay. Now I am confused. I have a bunch of virtual machines running under Virtual Box 3.2.12. I want to run them under KVM and drop Virtual Box from these systems. Supposedly "qemu-img convert" now supports direct conversion from vdi to whatever KVM uses. So I fired up the man page and got really confused. Then I fired up Google and got worse confused. Might I impose on

I've got a Samba member server as part of a Windows NT domain. User accounts have the same name in both domain. I was having all sorts of trouble when winbindd was running with wierd groups showing up. I happened to screw up the winbindd configuration without noticing causing it to crash, but I ran snmd and nmbd anyway and suddenly everything started working perfectly. The docs say you

m0<-epxression((4*theta1*theta2-theta3^2)/(2*x*theta3^2)-0.5*theta1*x) params<-all.vars(m0) this reads all the params from m0 so theta1,2 and 3 correct? params<-params[-which(params=="x")] checks which params are multiplied by x? np<-length(params) for(i in 1:6){ esp<-get(sprintf("m%d",i-1))

Solaris and/or ZFS are badly confused about drive IDs. The "c5t0d0" names are very far removed from the real world, and possibly they''ve gotten screwed up somehow. Is devfsadm supposed to fix those, or does it only delete excess? Reason I believe it''s confused: zpool status shows mirror-0 on c9t3d0, c9t2d0, and c9t5d0. But format shows the one remaining Seagate

Hi, I'm new to R, and I'm a bit confused with the "convolve()" function. If I do: x<-c(1, 2, 3) convolve(x, rev(x), TRUE, "open") = 9 12 10 4 1 But I expected: 3 8 14 8 3 (like in Octave/MATLAB - conv(x, reverse(x)) ) 3 2 1 x 1 2 3 = 3 2 1 0 6 4 2 0 0 9 6 3 = 3 8 14 8 3 The thing is, that "convolve(x, x, TRUE, "open")" works. For me

I would like to implement enum lookup in my dial plan but searching for solution / implementation I'm getting confused what is current standard. On some pages I read that the ENUMLOOKUP is not in development anymore and suggesting on using Enumlookup.agi scrip , some are saying that Asterisk 1.2.0 comes with a new powerful ENUMLOOKUP. So there is probably no need to use this script anymore;

Dear R colleagues, as a result of my calculations regarding the inter-observer-variability in bronchoscopy, I get a confusion matrix like the following: 0 1 1001 1010 11 0 609 11 54 36 6 1 1 2 6 0 2 10 14 0 0 8 4 100 4 0 0 0 0 1000 23 7 12 10 5 1001 0 0 4 0 0 1010 4 0 0 3 0 1011 1 0 1 0 2 11

Hi Im confused by one thing, and if someone can explain it I would be a happy > rev(strsplit("hej",NULL)) [[1]] [1] "h" "e" "j" > lapply(strsplit("hej",NULL),rev) [[1]] [1] "j" "e" "h" Why dossent the first one work? What is it in R that "fails" so to say that you need to use lapply for it to get

Why does R need the concept of "Vector"? In my opinion, it is a useless and confusing concept. A vector is simply a special case of a matrix whose row or column number is equal to 1. When I take submatrix from one matrix and if row or column number is 1, R will automatically convert it into a vector. It is very straightforward that a submatrix of a matrix should be a matrix. In

I'm trying to set up a first test for a dovecot + postfix (+ many other things) mail server for about 1000 accounts, and I keep stumbling on confusing inconsistencies in the HowTo documents I'm trying to follow. I tried to do a simple setup with virtual users using a howto saying it was for just that and that it's for Dovecot 2.x, and it shows a few text chunks to put in files,
