ylim in barplot()
Dear useRs,
I'm having troubles with using ylim in barplot(): even though I reduce
the y-scale using ylim, the bars still extend down to 0into the x-labels.
The sample data is below, and here is the code.
#This works fine but I would like to plot only from 50 to 70:
barplot(t(mydata), beside=TRUE, col=c("orange", "green", "yellow",
"purple"),

ylim in barplot()
If you are using a Windows system, you can Export the plot from RStudio and save it as a metafile without using package devEMF and it will crop the bars with xpd=FALSE. When I used devEMF on a Windows machine, the bars were not cropped with barplot() as you indicated, but when I switched to plotrix::barp() they were cropped. The arguments are a bit different, but I did not need xpd=FALSE:

ylim in barplot()
Thank you David,
That's a nice workaround using plotrix::barp(), but that doesn't explain
why ylim doesn't work as intended (or at least, as I expect it to work),
or why xpd has no influence when using devEMF::emf()...
The problem with saving directly in RStudio is that it requires to
manually save the plot, and this becomes troublesome when there are a
lot of plot commands in a

How to fit bivaraite longitudinal mixed model ?
Hi
Is there any way to fit a bivaraite longitudinal mixed model using R. I have
a data set with col names
resp1 (Y_ij1), resp2 (Y_ij2), timepts (t_ij), unit(i)
j=1,2,..,m and i=1,2,..n.
I want to fit the following two models
Model 1
Y_ij1, Y_ij2 | U_i = u_i ~ N(alpha + u_i + beta1*t_ij, Sigma)
U_i ~ iid N(0, sigu^2)
Sigma = bivariate AR structure
alpha and beta are vectors of order 2.

A statistical modeling problem
Hi,
This is not an R related question and I apologize for that, but given the
brain power of the R community it is hard for me to resist posting this
here.
I have a problem where each participant is shown a series of visual cues
(displayed on a computer screen in a random order) and asked to respond by
pressing a button (from a finite number of buttons) that corresponds to the

using virtualenv we can create an isolated environment in the system.
Just go through - http://docs.python-guide.org/en/latest/dev/virtualenvs/

%d empty even though username has @domain
hello,
Sorry to jump straight in with a question, but I've searched the
archive[0] and I'm pretty sure the answer's not there.
I'm using dovecot to replace courier imap, so authentication is by
vpopmail and the Maildirs are stored in the usual domains/domain/user/
Maildir. Everything seems to work very well, and setting it up has
been easy, so thank you very much for that.

One dovecot, multiple domains
Hey guys, I've got dovecot configured to work perfectly for virtual users across
different domains. It's great.
My problem is that, as far as I can tell, dovecot makes me use one SSL
certificate across all my domains. That's not what I want. Is there a way I can
get dovecot to use the cert for mail.foo.com when somebody is logging into a
foo.com account, and the cert for

ISDN Cause Code 47 Errors
We fairly recently switched service providers for our 4 PRI circuits. Since
that time, we started to notice some failed inbound calls. These calls
terminate with an ISDN cause code 47 'resource unavailble'. Most of the
time I see this error on the first or second channel on the second span in
a trunk group (This is the providers trunk group for hunting, not an
Asterisk trunk group). All

Echo on a PRI
Hi,
I recently set up the following in a production system (2.8 GHZ Xeon, 1 Gig
Memory, Dell 2650).
Telco - PRI - Asterisk - T1 - PBX
I am getting an occasional noticeable echo on some of the phone lines
(random inbound and outbound). Everyone I ask keeps telling me that I can't
be having echo since I am on a PRI, which is a digital circuit. Ok, so I
can't be having echo, but I am!

[PATCH] Provides a reference implementation management server.
The reference implementation server is based on TG2. The majority of the
boiler plate code has been stripped out to focus the server solely on
the functionality necessary for a management server.

setting value arg of pdSymm() in nlme
Dear All,
I wish to model random effects that have known between-group covariance
structure using the lme() function from library nlme. However, I have yet
to get even a simple example to work. No doubt this is because I am
confusing my syntax, but I would appreciate any guidance as to how. I have
studied Pinheiro & Bates carefully (though it's always possible I've

pdMat class in LME to mimic SAS proc mixed group option? Group-specific random slopes
I would like to be able to use lme to fit random effect models In which some but not all of the random effects are constrained to be independent. It seems as thought the pdMat options in lme are a promising avenue. However, none of the existing pdMat classes seem to allow what I want.
As a specific example, I would like to fit a random intercept/slope mixed model to longitudinal observations in
