Iterated Data Input/Output with Random Forests
Hi,
I am currently writing code to input a few thousand files, run them through the
Random Forests package, and then output corresponding results.
When I use the code below:

Problem with Random Forest predict
I am trying to run a partialPlot with Random Forest (as I have done many times before).
First I run my forest... Cell is a 6 level factor that is the dependent variable - all other variables are predictors, most of these are factors as well.
predCell<-randomForest(x=tempdata[-match("Cell",names(tempdata))],y=tempdata$Cell,importance=T)
Then I try my partial plot to look at the

flexible alternative to subsetting dataframe inside nested loops
I have a dataFrame variable:
L1 L2 L3 ... v1 v2 ...

I want to process subsets of it as defined by combinations of L1-L2-L3. I do
it successfully using nested loops:
for (i in valuesOfL1 {
for (j in valuesOfL2) {
for (k in valuesOfL3) {
tempData <- subset(dataFrame, (L1 == i & L2 == j & L3 == k,
select=c(v1,v2) ))

Re: [R-sig-finance] dates and times on Windows for fMetrics

MICE data analysis with glmulti
Dear All,
wonder if you have some thoughts on running the with() function (and perhaps including the pool() function to get the results?) in glmulti? In other words, how to run glmulti with a data set that is produced by mice()?
publicly available code:
data <- airquality
data[4:10,3] <- rep(NA,7)
data[1:5,4] <- NA
data <- data[-c(5,6)]
library(mice)

warnings messages from R when returning nothing
Hi : I have old Splus code that I am trying to turn into R
( I am using windows Xp and R 2.20 ) and I am getting a warning
from one of my statements because the behavior of R is different from Splus.
below, tempdata is a matrix of numbers and
I have the following command which basically runs through the columns and returns the minimum index of the column
where an NA occurs.

loading several "samples" of data from hard-drive, run "lm", "rlm", etc, save results in a list
I have many "sample" datasets (e.g. sample 5, sample 6, etc), each identified by a number as a suffix. These datasets are saved as individual R objects on my hard drive. (e.g."Wind.5.r" . "Wind.6.r","Solar.5.r","Solar.6.r") For example purposes, I have written code that creates similar data files using the "airquality" dataset. (see

plotting all subgroups with augPred
All,
I have a question RE plotting the prediction lines of a random effects
model via augPred. I'll illustrate via the Pixel dataset within the
nlme package:
library(nlme)
attach(Pixel)
fm1Pixel = lme(pixel ~ day + I(day^2), data = Pixel, random = list(Dog =
~ 1))
plot(augPred(fm1Pixel)) ### 10 fitted lines since there are 10 dogs
fm2Pixel = update(fm1Pixel, . ~ . + Side)

Filling Lists or Arrays of variable dimensions
Following problem:
Say you have a bunch of parameters and want to produce results for all combinations of those:

then what i used to do was something like this:
l<-list()
for(h in height){
l[[h]]<-list()
for(w in width){
l[[h]][[w]] <- doSomething()
}
}
Now those parameters aren't

augPred plot in nlme library

Fix for augPred/gsummary problem (nlme library)
Dear R-users,
I am a newbie to this site and a relative new-comer to S/R, so please tread lightly, for you tread...
There have been several posting relating to problems with augPred() from the nlme library. Here is a "fix" for one of these problems which may lie at the root of others.
In my case the problem with augPred() lay in gsummary(), which augPred() uses, causing it to fail.

augPred in lmer
I read the posts about augPred with lme, but does anyone know if there is a correlate for augPred for lmer? Specifically, I want to be able to use it to plot projections for all groups in an lmer class object using plot(augPred(lmer.object)).
Thanks,

How do I overlay two trellis plots of lme fitted lines produced by plot.augPred?
Hello,
I want to use lme to fit two (or more) models, and then compare the fits
on each individual. I know how to write my own code to do this (for each
individual, plot the raw data, followed by lines() to plot each fitted
curve) but I would like to use plot(augPred(... as it produces a nice
trellis plot. I thought I could do this with par(new=T) but it does not
seem to work.
