Online course- Mixed Effects Models
Dr. Andrzej Galecki will present his online course "Mixed
Effects Models with Applications" May 12 ? June 9 at
statistics.com.
This course will explain the basic theory of linear and
non-linear mixed effects models, including hierarchical
linear models (HLM). It will outline the algorithms used
for estimation, primarily for models involving normally
distributed errors, and will provide

question about getting things out of an lapply
Dear R-help subscribers,
I have a quite stupid question about using lapply. I have the following
function:
create.gradient <- function(i){
colorgrad01<-color.scale(seq(0,1,by=0.01), extremes=c("red","blue"))
tree1$edge[i,1] -> x
tree1$edge[i,2] -> y
print(x)
print(y)
all2[x] -> z
all2[y] -> z2
round(z, digits = 2) -> z
round(z2, digits = 2) -> z2

gradient generation
Dear R-help subscribers;
I have a question regarding making gradients in R. I've searched on the
web, but was only able to find functions that make a gradient between
color X and Y, which is not what I want.
I want to 'pick out' individual, smaller pieces of a gradient based on a
range of numbers. Say that I have a range of numbers, leading from 0 to
1. Then I want 0 to refer to

Pharmacokinetics using R
Hi,
I just wonder if R is still used for PK analysis. However, I have to use R
for some purposes anyways. Here is a really strange problem I am running
into and I hope to get some assistance from the group. The following code
works fine in S-Plus (Population estimates and MAP estimates look reasonable
).

saemix: SAEM algorithm for parameter estimation in non-linear mixed-effect models (version 0.96)
saemix implements the SAEM (stochastic approximation EM) algorithm for
parameter estimation in non-linear mixed effect models, used to model
longitudinal data.
Longitudinal data are particularly prominent in pharmacokinetics (study of drug
concentrations versus time) and pharmacodynamics (study of drug effect versus
time), but the SAEM algorithm has also been successfully applied in many

Re membering the last time an event occurred within a dataframe
All,
I am constructing a pharmacokinetic dataset and have hit a snag. The dataset
can be demonstrated in the following way:
myData <- data.frame(
evid = c(1, 0, 0, 0, 1, 0, 1, 1, 1, 0),
time = 1:10,
last.dose.time = c(1, 1, 1, 1, 5, 5, 7, 8, 9, 9)
)
The evid field is an indicator variable for whether the associated
observation is a dosing record (when it takes value 1) or an

nlminb( ) : one compartment open PK model
All,
I have been able to successfully use the optim( ) function with
"L-BFGS-B" to find reasonable parameters for a one-compartment
open pharmacokinetic model. My loss function in this case was
squared error, and I made no assumptions about the distribution
of the plasma values. The model appeared to fit pretty well.
Out of curiosity, I decided to try to use nlminb( ) applied to
