[R] R-Package for Recursive Partitioning without Classification or Regression

Hello, I have a question related to recursive partitioning, but I cannot find an answer, likely because I don't know how to properly word my Google search query. All recursive partitioning examples, which I can find, are used for either classification or regression trees like library(tree)

[R] Arules Package: Rules subset with 'empty' left hand side (lhs)

Hello, subsets of association rules (with respect to support, confidence, lift, or items) can be obtained with the arules::subset() function; e.g. rm(list = ls(all.names = TRUE)) library(arules) set.seed(42) x <- lapply(X = 1:500, FUN = function(i) sample(x = 1:10, size = sample(1:5,

[R] Radius of Curvature Fit

Hi there, I want to know the radius of curvature for a set of points, but cannot figure out how to perform the fit in R. I have a set of points P_i for which I want to calculate the radius of curvature. The coordinates (x_i|y_i) of the points in a data.frame: p <- data.frame( x = c(113, 143,

[R] Arules: R Crashes when running eclat with tidLists=TRUE

Hello, I'm using the eclat function of the arules package (1.0-6) for the identification of frequent itemsets. I need the tidLists, but if I set in the function tidLists=TRUE R crashes (Windows XP Professional SP3, 32 bit, R version 2.12.1 (2010-12-16), reproducible on two different computers) wit

Re: [R] Arules: R Crashes when running eclat with tidLists=TRUE

Update I had the chance to test the issue tonight using R version 2.12.2 on a Linux (Ubuntu 10.04.2, x86_64, kernel 2.6.32-32-generic) system: It does also crash (with a support of 0.01 instead of 0.05 posted earlier) running eclat(Adult, parameter=list(support=0.01, tidLists=TRUE)) but

[R] fgrep with caret (^) meta-character in system() call
