Re: [R] Unexpected behavior with weights in binomial glm()

way to tweak my glm() runs (possibly adjusting the numerical precision somehow???) so that this doesn't happen. Josh On Sat, Sep 29, 2012 at 7:50 PM, David Winsemius wrote: > > On Sep 29, 2012, at 7:10 AM, Josh Browning wrote: > >> Hi useRs, >> >> I'm exper

[R] Plotting DMAs (Direct Marketing Areas)

Hey useRs! Do any of you guys know how to plot DMAs within R (preferrably within the maps() package)? I haven't been able to find any resources on this, but I apologize if this is a dumb question and I'm overlooking the obvious answer. Thanks for your help! Josh [[alternative HTML vers

[R] Plotting US States: Issue with filled colors cycling

I'm having issues when trying to do a filled State plot using the maps() package. It seems that the color values aren't being plotted correctly, and I'm not sure why... I've started debugging it, but I'm stuck. I've attached the code that I've got so far. The for loop plots states 1:i. What I'

[R] Stratified Sampling with randomForest Regression

Hi All, I'm using R's randomForest package (and it's quite awesome!) but I'd really like to do some stratified sampling with a regression problem. However, it appears that the package was designed to only accommodate stratified sampling for classification purposes (see https://stat.ethz.ch/pipe

[R] Updating Neural Networks

Hi useR’s, I apologize if I’ve missed some documentation somewhere, but I can’t seem to find anything related to this question… For a ensemble/data-mining problem, I’m trying to train a neural network on my data set and have it output predictions (or coefficients) after varying numbers of epoch

[R] Pasting with Quotes

Hello useRs! So, I have a random question. I'm trying to build a character string, then evaluate it. I think an example would be the easiest way to explain: kern.vec = c("rbfdot","polydot") for( j in 1:length( kern.vec ) ) { formula= paste("ksvm( ind ~ . , data=d.temp[,c(

[R] rpart vs. tree and deviance calculations

Hi Everyone, I'm working on building some classification trees, and up to this point I've been using rpart. However, I recently discovered the tree package, and found that it had some useful functions (in particular deviance(), which I would really like to use for my project). I can't seem to

[R] Opening R in 64-bit version by default

Hi Everyone, This may be a dumb question, but I can't seem to figure it out. I have 32 and 64 bit versions of R installed on my machine, and I'd really like the 64-bit version to be the default (i.e. what opens when I open up a workspace). I've tried right-clicking on the workspace and setting t
