Hello everyone, I'm a newbie to R and to CART so I hope my questions don't seem too stupid. 1.) My first question concerns the rpart() method. Which method does rpart use in order to get the best split - entropy impurity, Bayes error (min. error) or Gini index? Is there a way to make it use the entropy impurity? The second and third question concern the output of the printcp() function.

Hi all, I apologies in advance if I am missing something very simple here, but since I failed at resolving this myself, I'm sending this question to the list. I would appreciate any help in understanding how the rpart function is (exactly) computing the "improve" (which is given in fit$split), and how it differs when using the split='information' vs split='gini'

Dear everybody, I'm a new user of R 2.4.1 and I'm searching for information on improving the output of regression tree graphs. In the terminal nodes I am up to now able to indicate the number of values (n) and the mean of all values in this terminal node by the command > text(tree, use.n=T, xpd=T) Yet I would like to indicate automatically in the output graph of the tree some

Hi, this should be an easy one, but I can't figure it out. I have a vector of tests, with their units between brackets (if they have units). eg tests <- c("pH", "Assay (%)", "Impurity A(%)", "content (mg/ml)") Now I would like to hava a function where I use a test as input, and which returns the units like: f <- function (x) sub("\\)",

Hi Suman, I think you can ascertain pureness automatically leveraging the compiler instead of manually tagging attribute to each method and call-site. It would seem like impurity should be a transitive attribute. So this would conflict with below. __attribute__((annotate("pure"))) int add(uint32_t a, uint32_t b) { // impure by calling printf... ... printf("%d + %d =

Good afternoon Support Team, I have discovered a disturbing error inside?anaconda-ks.cfg under the /root directory. Examination found the config file devoid of the string "buns". It's distressing, because I don't understand how my Anaconda can get anything done if it doesn't happen to have any buns. Please advise I need to know how to continue. Please feel free to contact me

Hi, I'm doing a function that describe two populations in competition. that's the function that i wrote: exclusao<-function(n10, n20, k1, k2, alfa, beta, t){ n1<-k1-(alfa*n20) n2<-k2-(beta*n10) if(t==0){plot(t, n10, type='b', xlim=range(c(1:t),c (1:t)), ylim=range(n10, n20), xlab='tempo', ylab='tamanho populacional') points(t, n20, type='b',

Hello everyone, I have biological data from a competition experiment where a free ligand is titrated against the binding of a protein. Now, I would like to fit a standard on-site binding curve to this data in order to obtain the IC50 and Kd values. Unfortunately I have not been able to find a package/function which allows such a fitting and calculates the results. Does anyone know if there is

Hello everyone. There is a new competition, outlined on the blog dataists<http://www.dataists.com/2010/10/using-data-tools-to-find-data-tools-the-yo-dawg-of-data-hacking/>, inviting us to analyse statistics of the use of R packages (collected from 52 R users), to create a R-package suggestion engine for ourselves. Since I noticed several bloggers already wrote about it (as I have detailed

Dear R-help Listers, The following two student competitions are of interests to the now many student R package developers. I'd appreciate your help in spreading them. #1. John M.

Dear R, Short verse of the question: Is there R code which will calculate surrogate splits and/or delta impurity for decision trees at each node? Long Version: I have local, legacy code which I use to calculate my decision trees. I would like to switch to R, but as I understand it surrogate splits are not implemented. Surrogate splits and feature ranking are described in Breiman et al

Unless someone already has a snazzy isolinux image that lets you select multiple makes and models to update bios's that's willing to share. I was curious if someone could tell me how to go from my isolinux.cfg into sub menu categories so instead of having one great big menu with multiple makes models and bios revisions, I can drill down into menu's until i get to the bios revisions to

Hi, I'm putting some promotional material together and noticed that most proprietary codec manufacturers have a nice eye-catching memorable logo. Does the CELT codec have a snazzy logo that I can use as a nice memory aid when telling people how great the codec is? thank you, Paul.

After googling a bit, it seems that only way samba playes with active directory is with samba 3.x I'f been use samba 2.x with 'pass through' authentication and would like to get rid of the pass through auth cause it seems to cause problems. Yet, I don't know if I can trust samba 3 -- Has anyone been able to get a samba 2.x server to join a an Active Directory domain? My

Hi recently bought a soekris net5501 and a tdm410 to place in there. I am having some issues attaching 12V power to the card via the molex card - basically the box for the motherboard is too small. I have read up about a PWR2400b and it seems to use 2wire pin, I am guessing to connect to P8 just behind the molex connector on the tdm410. can any one here confirm this, or have any info on the
