[R] step function stops with "subscript out of bounds"

I've been having a problem using the step function to evaluate models. I've simplified the code and get the same problem using the dataset Titanic. The relevant code and output is below. The problem disappears (i.e., 'step' runs correctly) if I rerun the code but change the 'loglm' call to explicit

[R] step function

Hi All I need some help with plotting a step function, currently I'm using sfun <- stepfun(c(1, 2, 5,10, 20), c(0, 11, 22, 33, 44, 0), f=0) plot(sfun, pch=NA, main="", xlim=c(1,20)) which I working fine, but my data is in the following format: Min Max Value 1 2 11 2 5 22 510 33 10 20 44 1. To

Hello I am using the step function in order to do backward selection for a linear model of 52 variables with the following commands: object<-lm(vars[,1] ~ (vars[,2:(ncol(predictors)+1)]-1)) BackS<-step(object,direction="backward") but it isn't dropping any if the variables in the model, but there

Re: [R] Step Function Freezing R

Can you think of any systemic changes that might interefere with R besides Symantec EndPoint and LiveUpdate? I have removed those programs and allocated more memory to R, but it is still way too slow. On Nov 13, 10:45 pm, J Dougherty wrote: > On Friday 13 November 2009 07:17:28 am Jgabriel wrote:

Re: [R] Step Function Freezing R

Alright, here's the update: the IT guy insists that the RAM is not the problem. RAM, according to him, is "pretty black and white". There should be enough RAM on the system for the function to work, and he was the one who installed the extra RAM in the first place. Could there be another RAM issue

Re: [R] Step Function Freezing R

There are some points of information you should include. One, have there been recent updates of Windows that may have altered system behaviour? Two, have you updated R during the same period? Three, have you installed software that uses system resources that were available to R before - e.g.

[R] Step Function Freezing R

I have a question that might not be "kosher" here, but I'm running out of options and need some help. Basically using the function "step" is freezing R. I am running a model that includes a number of interactions on a large data set with a number of dummy variables representing whether an event occ
