...he chkconfig used by RHEL and clones too. Also, maybe it should be installed by the Makefile's install target? it could then also set: DAEMON=/path/to/dovecot/daemon instead of: DAEMON=/usr/local/sbin/dovecot Cause naturally, it will know the prefix chosen. May the source be with you, Jess Portnoy

...e there is the locution: if(!requireNamespace("survival", quietly = TRUE)) stop("crq requires survival package to be installed") However, when R CMD check tries to do one of the crq examples I see: > f <- crq(Surv(y,d,type = "left") ~ x, method = "Portnoy") Error in eval(expr, envir, enclos) : could not find function "Surv" Calls: crq ... eval -> model.frame -> model.frame.default -> eval -> eval Execution halted Can someone suggest a fix?

Hi, I have Win XP 32, 4 gig DDR2 and R 2.9.2. I have memory limit problems. > memory.limit(4090) [1] 4090 > memory.limit() [1] 4090 > a<-trans.matrix.f(7) # made big matrix of integer 16384*16384 Error: cannot allocate vector of size 512.0 Mb I not have other objects in R memory. what I do? trans.matrix.f <- function(x){ tr.mat <- matrix(c(0,1,1,0),2) for(i in 2:(2*x))

...s of X, with nonparametric components defined as functions of z1 and z2. Rather than estimating conditional mean functions, conditional quantile functions are estimated using penalty methods. When z1 is univariate fitting is based on the total variation penalty methods described in Koenker, Ng and Portnoy (Biometrika, 1994). When z2 is bivariate fitting is based on the total variation penalty (triogram) methods described in Koenker and Mizera (2003), available at http://www.econ.uiuc.edu/~roger/research/goniolatry/gon.html and forthcoming in JRSS(B). There are options to constrain the qss componen...

I will be giving a course in survival analysis using R (of course!) for people who know nothing about the subject (including R), but know basic statistics. I'm looking for a suitable course book. Therneau & Grambsch (2000) is an excellent book, but too much for this course. I need somthing more elementary. I have a vague memory saying that such books exist, but I cannot find any for the

Hi, I'm looking to perform a classification analysis on an imbalanced data set using random Forest and I'd like to reproduce the weighted random forest analysis proposed in the Chen, Liaw & Breiman paper "Using Random Forest to Learn Imbalanced Data"; can I use the R package randomForest to perform such analysis? What is the easiest way to accomplish this task? Thanks,

Hi, I was recently plowing through the docs of the quantreg package by Roger Koenker and came across the total variation penalty approach to 1-dimensional spline fitting. I googled around a bit and have found some papers originated in the image processing community, but (apart from Roger's papers) no paper that would discuss its statistical aspects. I have a couple of questions in this
