post hoc in repeated measures of anova
Hallo, I have this dataset with repeated measures. There are two
within-subject factors, "formant" (2 levels: 1 and 2) and "f2 Ref" (25
levels: 670, 729, 788, 846, 905, 1080, 1100, 1120, 1140, 1170, 1480,
1470, 1450, 1440, 1430, 1890, 1840, 1790, 1740, 1690, 2290, 2210,
2120, 2040, 1950), and one between-subject factor, lang (2 levels:1
and 2). The response variable

From NUM to INT
Dear all:
I converted the columns (Baci, Meti, Fungii, Protozoai) into integers
(using excel) and then imported the data (.txt) into R. Interestingly, the
other three variables were loaded as INT, but the 'Baci' one continued as
Num.
I imported the data using the following command line:
X <- read.delim(file.choose(),
header = TRUE,
dec =

Can you explain why you need them as 'integer', A floating point
representation can hold a value upto ~4.5e15 as an "integer" keeping the
precision that you might need.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

From NUM to INT
Ok. I`m trying to run a Poisson glmm with an observation-level random
intercept. But I`m getting the following error for the 'Baci' variable:
'Error: (maxstephalfit) PIRLS step-halvings failed to reduce deviance in
pwrssUpdate'. I guess this message is because the baci variable is not a
an integer, and cannot be transformed into an integer as R has a threshold
of
2x10^9 even in

lm( y ~ A/x ) ... how do I extract the coefficients by factor?
When regressing by month, how do I get the coefficients out into a new data
set?
I'm looking for
[ month, a, b, c ]
from the Pastor-Stambaugh model I'm using which is:
r[i+1] = a + b * r[i] + c * v[i] + e
the model I'm using wants to create a new dataseries based on the
coefficient in each month. I'm doing a simple linear regression on DataSet,

'geepack' and 'gee' package outputs
Hi, having used both the gee pacakge and the geepack package, i am unsure of
how to interpret the results.

Please respond to the list. It will be obvious why in a second.
That's not my threshhold! -- it's R's. Your numeric integers cannot be
exactly represented as integers in R. Period. Maybe there are special
packages for extended arithmetic that can do this. but someone else
would have to help you there. See here for a discussion that might be
helpful:

glm StepAIC with all interactions and update to remove a term vs. glm specifying all but a few terms and stepAIC
Problem:
I am sorting through model selection process for first time and want to make
sure that I have used glm, stepAIC, and update correctly. Something is
strange because I get a different result between:
1) a glm of 12 predictor variables followed by a stepAIC where all
interactions are considered and then an update to remove one specific
interaction.
vs.
2) entering all the terms

Nested model - "singularities not defined"
I am using a nested model in R and the lm output shows 47 not defined
because of singularities and I have no idea why. Any help on why this is
happening or how to fix this problem would be very much appreciated. Below
is the output I received from R.
Thanks and happy holidays!

[plyr] Moving average filter with plyr
Dear all,
I'm stuck with a problem using plyr to process a rather large junk of data. What I'm trying to do is applying a moving average to all the subparts of the dataframe (the example data can be found here https://dl.dropboxusercontent.com/u/2414056/testData.Rdata).
require(plyr)
load("testData.Rdata")
applyfilter<-function(x){
return(filter(x,rep(1/5, times=5)))

How to Populate List
Hi,
I'm new to R and would like to know, how one can populate the list with array data.
I'm reading a tab separated table in R. The data in the table looks something like this.
#Table Data
Comp A B C
Extracellular 103 268 535759
Nucleus 45603 47783 442744
