Dear R Programmers! After some time of using R I decided to work through John Chambers book "Programming with Data" to learn what these S4 classes are all about and how they work in R. (I regret not having picked up this rather fine book earlier!) I know from the documentation and the mailing archives that S4 in R is not 100% the book and that there are issues especially with

Hello guys.I just read up about tf-idf schemes and want to implement it in Xapian (with some frequently used normalizations) as it will also give me a good hang of implementing a weighting scheme before I start working on implementing DFR schemes. I read the following as references and I think Ive understood it well and can write the hack :- 1.)

Hi Ian, Per your suggestion, I reinstalled R 2.9.0, then I reinstalled ggplot2 on top. The problem persists. Here's the what happens after the installation: > qplot (carat, price, data = diamonds, alpha = I(1/10)) Warning message: In grid.Call.graphics("L_points", x$x, x$y, x$pch, x$size) : semi-transparency is not supported on this device: reported only once per

Dear list, I am using rsync with Ubuntu: clients use 7.04 LTS (rsync ?version 2.6.9 ?protocol version 29) server has 9.04 (rsync ?version 3.0.5 ?protocol version 30) I am working with rsync and I notice 2 strange behaviors: the fist one is already described in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=536078 , but I don't find any reply the second one, when parsing log file,

I appear to have hit one of the "drop" issues raised in some discussions a couple of years ago by Frank Harrell. They don't seem to have been fixed, and I'm under some pressure to get a quick solution for a forecasting task I'm doing. I have been modelling some retail sales data, and the days just after Thanksgiving (US version!) are important. So I created some dummy

It depends on

Hello guys.I am working on implementing the PL2 weighting scheme of the DFR framework by Gianni Amati. It uses the Poisson approximation of the Binomial as the probabilistic model (P), the Laplace law of succession to calculate the after effect of sampling or the risk gain (L) and within document frequency normalization H2(2) (as proposed by Amati in his PHD thesis). The formula for w(t,d) in

Hi, This implementation looks fine, but there is no specification for using SM3 in the SSH protocol. Could I suggest that you start by talking to the IETF to get the standardisation process started? https://mailman3.ietf.org/mailman3/lists/ssh.ietf.org/ is a good mailing list to start at. There have been recent conversations in the IETF about how best to handle national cryptographic standards

I have assayed the concentrations of various metal elements in different anatomic regions of two strains of mice. Now, for each element, in each region, I want to do a t test to find whether there is any difference between the two strains. Here is what I did (using simulated data as an example): # create the data frame > elemconc = data.frame(expand.grid(id=1:3, geno=c('exp',

Hello, I'm having problems working with date values in POSIXct format. Here is what I got (eg.lig attached): x <- read.table("eg.txt", sep = ',', col.names=c("ok","time","secs","lig")) # it gives time as factor z <- cbind(x,colsplit(x$time, split="\\s", names=c("date", "clock")))

Dear all, I'm looking to create a formula within a function to pass to glmer() and I'm having a problem that the following example will illustrate: library(lme4) y1 = rnorm(10) x1 = data.frame(x11=rnorm(10), x12=rnorm(10), x13=rnorm(10)) x1 = data.matrix(x1) w1 = data.frame(w11=sample(1:3,10, replace=TRUE), w12=sample(1:3,10, replace=TRUE), w13=sample(1:3,10, replace=TRUE)) test1 <-
