Dear devellopeRs, I've altered factor.scope() from the stats package so it can take marginality into account. Therefore I've added the argument marginal. When marginal is NULL, factor.scope() works like the original version. The marginality is to be specified as a named list. The name of the elements is the name of a variable. The content of the element is a character vector with the

Dear developers, I just noticed that step() function currently prints the current model using message(), but the resulting model using print(). The relevant commands within the step() body are: if (trace) message("Start: AIC=", format(round(bAIC, 2)), "\n", cut.string(deparse(as.vector(formula(fit)))), "\n") (with example() output:) Start: AIC=190.69

Dear List Members, I have encountered two problems when using the step function to select models. To better illustrate the problems, attached is an R image which includes the objects needed to run the code attached. lm.data.frame have factor variables with 3 levels. The following run shows the first problem. AICs (* and **) are different. I noticed that the Df for rs13482096:rs13483699 is 4,

Dear all, I have tried to modify the code of MASS:::stepAIC.default(), dropterm() and addterm() to use AICc instead of AIC for model selection. The code is appended below. Somehow the calculations are still not correct and I would be grateful if anyone could have a look at what might be wrong with this code... Here is a working example: ## require(nlme) model1=lme(distance ~ age + Sex, data =

Hello, I am trying to recursively append some data from multiple files into a common object For this, I am using in a loop NewObject <- rbind(NewObject,tempObject) For the first loop, obviously there is no NewObject ... so I wanted to do NewObject <- tempObject[0,] Now when it loops again I want to put the statement do "NewObject <- tempObject[0,]" inside a if statement

Dears, I have a question about copying reference objects using the initialize method. 1) If the latter has no arguments, there is no problem to copy an object. myClass = setRefClass("myClass", fields = list(value = "numeric") ) myClass$methods(initialize = function(...){ ? value <<- 1 ? callSuper(...) }) newObject = myClass$new() newObject$value = 2 copyObject =

I was cursing Matlab again today (what else is new) because the default action for every Matlab command is to spew the result to the console, and one must remember to put that darn ";" at the end of every line. So I just wondered: was there ever a discussion as to providing some modified version of the "<-" and "->" operators in R to do the reverse?

I need some help in defining a "print" method for my new S4 class definition. So fer I have worked like this: setClass("MyClass", sealed=F, representation(slot1 = "list", #create a new class slot2 = "vector", slot3 = "vector", slot4 = "vector")) setMethod("print",

The question is whether a pointer value, reference, or name is formally forwarded to point to the new object. Because the dynamic type is different, the pointer value held in 'p'

Hello. I'm new to this forum. Before I posted this, I did due diligence searching for an answer to my problem. I found and tried 2 possibles; but neither would work for me. First my machine specs: 64 machine dual boot between WinXP and Ubuntu Janty Jackalope 9.04. When I used Hardy Heron 8.04 last year, I was able to install Version 7.0 of Dreamweaver MX on a fluke.. I still don't know

At the end of a for loop its variables are still present: for (i in 1:10) { x <- vector(length=100000000) } ls() will print "i" and "x". this means that at the end of the for loop body I have to write rm(x) gc() is there a more elegant way to handle this?

Dear peRsons, I have a Sweave document which demonstrates the usage of step() function. With current R version 2.5.0 the step() function was changed so that the heading of trace=TRUE output for each model is printed using command message(): if (trace) message("\nStep: AIC=", format(round(bAIC, 2)), "\n",

Hi again List, Well this time I’m writing for a friend (really J). He needs to create a distance matrix based on an abundance matrix using the 1-Pearson’s R index. Well I told him to look at the proxy package, but there is only Pearson Index. He needs it to perform a clustering. Well, as soon as he told me there proxy only had the Pearson index I thought: “He could just do something like

I''m having this problem with IE and getElementsBySelector, but am a relative js novice, so quite possible -- likely even -- that I''m doing something stupid. Either way, a fresh pair of eyes would help. Basically I''m duplicating a fieldset within a form (so you can upload more than one photo). [BTW, the fieldsets have a CSS id which relates to the object id of the
