Lme does not work without a random effect (UNCLASSIFIED)
Classification: UNCLASSIFIED
Caveats: NONE
Dear R users,
I'm interested in finding a random effect of the Block in the data shown
below, but 'lme' does not work without the random effect. I'm not sure how
to group the data without continuous value which is shown in the error
message at the bottom line. If I use 'aov' with Error(Block), is there a
test method comparing

substring comparison
Hi all,
I'm writing a script to do some basic text analysis in R. Let's assume
I have a data frame named data which contains a column named 'utt'
which contains strings. Is there a straightforward way to achieve
something like this:
data$ContainsThe <- ifelse(startsWith(data$Utt,"the"),"y","n")
or
data$ContainsThe <-

Training parameters for a HMM
Hi,
I'm a newbie to the world of HMMs and HMMs in R. I've had a look at
the hmm package and the RHmm package but I couldn't see anything
straightforward on how a labelled sequential dataset with observed
values and underlying states might be used to construct and train a
HMM based on that data and no pre-computed values for the transition,
emission or initial state distributions. Does

Strange Share Trouble
I am running SAMBA on Redhat Linux 7.x.
I have a share for our office as a file server. The regular Win9x client
can browse / edit / delete and use the server with no issues from the
Windows Explorer / Applications except for one.
We run AutoCAD (drafting) with an extension Cadpipe. Cadpipe has it's own
file browser style interface where you add files to a list to create a

Newbie-ish question on iteratively applying function to dataframe
Hi,
I am trying to recursively apply a function to a selection of columns
in a dataframe. I've had a look around and from what I have read, I
should be using some version of the apply function, but I'm really
having some headaches with it.
Let me be more specific with an example.
Say I have a data frame similar to the following
A x y z r1 r2 r3 r4

ANOVA of a sort
Dear R Help,
I have a general question - I know this is the R list, but I hope
someone can help me out a little as I've always found the help here to
be absolutely fantastic.
I have run a psychological study where participants are given multiple
stimuli and their responses to those stimuli are measured on the same
numerical scale, i.e., the data is something like

Summary Regard with Lme does not work without a random effect (UN CLASSIFIED)
Classification: UNCLASSIFIED
Caveats: NONE
R users,
This is a summary for the responses I got from Sandra Dorai-Raj and Simon
Blomberg followed by my question.
Sandra suggested using lm instead of lme for a model without a random
effect, and Simon suggested anova.lme instead of anova.lm for comparing two
models with and without a random effect. For the anova test, both anova.lme

Practical work with logistic regression
Dear all,
I have a couple of short noob questions for whoever can take them. I'm
from a very non-stats background so sorry for offending anybody with
stupid questions ! :-)
I have been using logistic regression care of glm to analyse a binary
dependent variable against a couple of independent variables. All has
gone well so far. In my work I have to compare the accuracy of
analysis to a C4.5

Desperate Help Required Getting SAMBA back on line

I am still a bit of a newbie and I am having trouble troubleshooting this. I really am in

Density function for non-central t distribution
Hi,
I've written some C code for density evaluation of the non-central t distribution. It works
with the R-1.7.1 source code if placed in the src/nmath directory and after appropriate
changes are made to Makefiles, to the dt function in src/library/base/R/distn.R etc.
I haven't read a lot of R source code so it may need some R-ification, but I've tried to use the
dt.c file as a

Not working. But what is wrong? I've added the second mount to

point. The mount part of icecast.xml:

multi-class classification using rpart
Hi,
I am trying to make a multi-class classification tree by using rpart.
I used MASS package'd data: fgl to test and it works well.
However, when I used my small-sampled data as below, the program seems
to take forever. I am not sure if it is due to slowness or there is
something wrong with my codes or data manipulation.
Please be advised !
The data is described as the output from str()

Switch back to mount after fallback
Hello icecast user,
That's my first post to this list, because everything works fine :) But
now I'm missing a feature and I'm not sure if it is possible to realise.
I have two mounts. Only one defined in the configuration:

Games-Howell, Gabriel, Hochberg
Hello,
I read a book about statistics in psychology. The authors use SPSS. They
talk about post hoc tests after ANOVA finds significant effects:
- Gabriel's procedure (for equal or slightly different sample sizes)
- Hochberg's GT2 (for different sample sizes)
- Games-Howell procedure (for populations with unequal variances)
I could not find them in R. Do they not exist in R

Web application to feed icecast
Hello,
i guess this question appeared before, but I haven't found anything by

I know that some web radio stations use icecast2. They also have a web
application that makes it possible to request songs, add items to the
playlist of the source client and so on. Most of the web radios have
developed the web application by itself (i guess so).
