...but I can't add the spline, a overall trend line. In the SAS code they use the command 'I=SM50S' and I would prefer something similar. I?m using R 2.10.1 on windows XP? I have made this working example. tolerance.pp <- read.table("http://www.ats.ucla.edu/stat/R/examples/alda/tolerance1_pp.txt ", sep=",", header=T) # install.packages("lattice", dep = T) library(lattice) xyplot(tolerance ~ age, groups = id, data=tolerance.pp, type = "l") This is where I want to add a overall spline. Hope someone out there can figure this out. Thanks...

Hi, I am trying to plot an interaction.plot with different color for each level of a factor. It has an erratic behavior. For example, it works for the first interaction.plot below, with the example from the ALDA book, but not with the other plots, from the NPK dataset: # from http://www.ats.ucla.edu/stat/r/examples/alda/ch2.htm tolerance <- read.csv("http://www.ats.ucla.edu/stat/r/examples/alda/data/tolerance1.txt") tolerance.pp <- read.csv("http://www.ats.ucla.edu/stat/r/examples/ald...

...'s not fully tested or there will be some important fixes before 7.0 final? We are going to try different RAID combinations but it definitely not working using 6x146GB as RAID5. Maybe someone could share the RAID combinations they successfully are running on? Thanks in advance. Kind Regards, Aldas

Hi, Try either: tolerance <- read.csv("http://www.ats.ucla.edu/stat/r/examples/alda/data/tolerance1.txt") ?aggregate(exposure~male,data=tolerance,mean) ?# male exposure #1??? 0 1.246667 #2??? 1 1.120000 #or ?library(plyr) ?ddply(tolerance,.(male),summarize,exposure=mean(exposure)) #? male exposure #1??? 0 1.246667 #2??? 1 1.120000 #or with(tolerance,tapply(exposure,list(m...

Hi, Now i am dealing with longitudinal data set and I want to see the rough marginal plot for 2 variables separately. I found the code from one example here, reading <- read.table("http://www.ats.ucla.edu/stat/R/examples/alda/data/reading_pp.txt", header=T, sep=",") reading[reading$id %in% c(4, 27, 31, 33, 41, 49, 69, 77, 87), ] xyplot(piat~age | id , data=reading[reading$id %in% c(4, 27, 31, 33, 41, 49, 69, 77, 87), ],panel=function(x,y,*subscripts*){ panel.xyplot(x, y, pch=16) panel.lmline(x,y...

I am having a hard time understanding how to perform a "repeated measures" type of ANOVA with R. When reading the document found here: http://cran.r-project.org/doc/contrib/Lemon-kickstart/kr_repms.html I find that there is a reference to a function make.rm () that is supposed to rearrange a "one row per person" type of frame to a "one row per observation" type

Dear R-help list members I gathered longitudinal data on fish behaviour which I try to analyse using a multi level model for change. Mostly, I am following Singer & Willett (2003), who provide also the S/R code for their examples in the book (e.g. http://www.ats.ucla.edu/stat/Splus/examples/alda/ch4.htm). Of course I am interested in change over time, but I am also very much interested in consistency of behaviour of individuals, that is, does an individual for example show consistent levels of aggression and differ from others in a consistent manner. I thought that I could tackle this ques...

I have been working through the book "Applied longitudinal data analysis: modeling change and event occurrence" by Judith D. Singer and John B. Willett. I have been working examples using SAS and also using it as an opportunity for learning to use R for statistical analysis. I ran into some difficulties in chapter 8 which deals with using structural equation modeling. I have tried to

Hi R users! I am trying to learn some multilevel analysis, but unfortunately i am now very confused.
