How to write random effect in MCMCglmm
Hi All,
The data set that I have is a cluster data, and I want to run a HLM mixed
model with multi-level response. Here is my data set:
response:
- Level (num: 1, 2, 3, 4, 5 - 5 levels)
Covariates:
- Type (Factor: A, B, C - 3 levels)
- yr (num: 2006, 2007, ...)
- Male (num: 0=not Male, 1=Male - 2 levels)
- Ethnicity (Factor: A, B, H, ..., - 7 levels)
- ELL (num: 0, 1, - 2

help with legacy R code
Hi there,
Could somebody help me disect this legacy R script I inherited at work, I

1. I've tried to upgrade our R version from 1.6.2 (yeah, I know), to R 2.0,
but some of the lines in this script are not compatible with R 2.0, could
someone help me figure out where the problem is?
2. the jpeg generated (attached) seems to be off on some of the data, is
there a better way

glm and plot.effects
Dear R-helpers,
I don't see a difference between the following two plots of effect
objects, which I understand should be different. What am I missing?
require(doBy)
require(effects)
data(budworm)
m1 <- glm(ndead/20 ~ sex + log(dose), data=budworm, weight=ntotal,
family=binomial)
m1.eff <- all.effects(m1)
plot(m1.eff, rescale.axis = FALSE, selection = 2, main = 'rescale =

two indirect effects of path analysis
Hello,
This is Elaine.
I am trying a path analysis using lavaan Package.
There are three explanatory variables: X, Z, and M.
The response variable is Y.
A, b, and c have direct effects on Y.
On the other hand, X and Z also have direct effects on M.
In other words, X and Z have indirect effects on Y.
I found the code example of lavaan package describes only one indirect
effect as below.
Please

chisq.test on samples of different lengths
Hello,
I am trying to see whether there has been a significant difference in whether people experienced damages from wildlife in two different years. I therefore have two columns:
year 1:
yes
no
no
no
yes
yes
no
year 2:
no
yes
no
yes
I wanted to do a chisq.test, but if I enter it this way:
chisq.test(year1, year2)
I get the error saying the columns are two different lengths. So then I tried

Help with for/if loop
I have a set of data that includes various data columns. One if the survival
time and another if a continuous variable of ages. I want to put the ages
into intervals so that I can then perform the Kalpan Meier test. I am trying
to use the following code to build a column with the age group numbers in
agecatagory<-c( )
for (i in 1:137)

Possible to "import" histograms in R?
Hi,
I have a large amount of data that I would like to create a histogram of and
plot and do things with in R. It is pretty much impossible to read the data
into R, so I have written a program to bin the data and now have a list of
counts in each bin. Is it possible to somehow import this into R and use
hist(), so I can, for instance, plot the probability density? I have looked

new package proptest
Dear R users,
The package proptest (http://www.davidkraus.net/proptest/) has been
recently released to CRAN.
The package provides functions for testing the proportional hazards
assumption in the Cox model for right censored survival data. Two types of
tests for identifying nonproportional covariates are implemented:
* data-driven Neyman type smooth tests (using both nested and all-subsets
