I have a multiple text files, separated by a single space, that I need to combine into a single data.frame. Below is the track I'm on using list.files to capture the names of the files and then lapply with read.table. But I run into problems making a usable dataframe out of the data. #Creating example data in similar format to data I have sub <- rep(1,10) trial <- seq(1,10,1) size

*Respected Sir, I have a simple question regarding plots of time series in R. I have to plot "conc" against "time" **for each individual and display in the same panel for the in-built dataset "Indometh" in R. * ***I have six time series, say subject1.ts, subject2.ts, ............., subject6.ts. The observations are taken at an interval of 0.25 hr. All of the series

I am trying to specify a mixed model for my research, but I can't quite get it to work. I've spent several weeks looking thru various online sources to no avail. I can't find an example of someone trying to do precisely what I'm trying to do. I'm hoping some smart member of this mailing list may be able to help. First off, full disclosure: (1) I'm an engineer by trade, so

I get the following message when using the reshape2 package line > tDat.m<- melt(Dataset) Using Item, Subject as id variables > tDatCast<- acast(tDat.m,Subject~Item) Aggregation function missing: defaulting to length Note Problem Statement- convert dataframe Subject Item Score 1 Subject 1 Item 1 1 2 Subject 1 Item 2 0 3 Subject 1 Item 3 1 4 Subject 2 Item 1 1 5

I postulate the following model AC <- glmer(Accuracy ~ RT*Group + (1+RT|Group:subject) + (1+RT|Group:Trial), data = da, family = binomial, verbose = T) Here I predict Accuracy from RT, Group (which has values 0 or 1) and the interaction of Group and RT (those are the fixed effects). I also estimate the random effects for both intercepts and slopes for subjects and different trials.

Hello everybody, I need an help because I don´t know if the command for the ANOVA analysis I am performing in R is correct. Indeed using the function aov I get the following error:"In aov (......)

Hi, I'm trying to understand R's object oriented abilities. I have read (in a very recent email to r-help) that R's methods package does not support private methods. However, I also looked at the source for the function "is": > is function (object, class2) { cl <- .class1(object) if (missing(class2)) return(extends(cl)) if (.identC(cl, class2)

I'm trying to use tapply to output means and SD or SE for my data but seem to be limited by how many times I can subset it.

I have two objects that are associated in the following way: class Class1 < ApplicationController has_and_belongs_to_many :class2s has_and_belongs_to_many :otherClasses end class Class2 < ApplicationController has_and_belongs_to_many :class1s has_and_bleongs_to_many :otherClasses end Now, when I run the following query, @objects = Class1.find(:all, :conditions

> To find which header files could be removed it scanned the file for "#include" lines and tried to remove them one by one (checking if the file still compiles after the removal). When there were no more include lines to remove, we verified the change with ninja+ninja check. It looks like this makes us rely heavily on transitive header includes -- is that right? Specifically what I

I keep expecting R to have something analogous to the =count function in Excel, but I can't find anything. I simply want to count the data for a given category. I've been using the ddply() function in the plyr package to summarize means and st dev of my data, with this code: ddply(NZ_Conifers,.(ElevCat, DataSource, SizeClass), summarise, avgDensity=mean(Density),

I has several model objects that flow down like a tree: Class1 has_many Class2 Class2 has_many Class3 and so on. when are the child records actually created? If I do: c1 = Class1.find(:all) are the child objects (C2s below) created then or not until i do something like: c2s = c1.C2s while iterating through the c1s? If the form, that''s cool, no problem, but If I''ve got
