need help with errors in betareg analysis
Hi
I'm trying to fit a model in betareg and I'm getting errors, but have no
idea what they mean or how to solve them. Does anyone have experience with
this?

Extracting elements of model output
I am having difficulty extracting specific results from the model
object. The following code shows where I am stuck.
I want to run resamplings of a data set. For each I want to extract a
particular F for the contrasts. If I run a very simple model
(e.g. model1 <- aov(time~group) ) I can get the relevant coefficients,
for example, by using "model1$coefficients". That's fine.

Diagnosing IPv6 routing
I discovered that IPv6 is sort of working when I got an email rejection
from Comcast for not having an IPv6 PTR record. I discovered I could telnet
to port 25 on their MX server over IPv6! I then found I could tracroute6 to
them, but I couldn't to my Linode VPS in Fremont. It gets to the data
center and stops. Going the other way, my Linode can traceroute6 almost to
my AT&T-hosted

problem with data
Hello all!
I have a problem with my data in R. When I want to plot the following data,
I have a problem with y scale. The maximum value is cc. 10 degrees and in R
is about 100.
I use this code:
fasy<-read.table("gridd1.txt",sep="\t",dec=",",header=T,row.names=1)
# here are the years:
x <- as.numeric(rownames(fasy))
# extract a series that you want to plot:

Is this a bug in smbclient?
Hi there,
im trying to backup a Windows Server 2003 64Bit with Amanda. It uses the smbclient for backing up a Windows Share.
So far so good, but on large shares I do get a lot of error messages which I can not explain.

FW: multivariate regression
The test is manova. I tried to use manova() function, I used the code below:fit <- manova(Y ~ X)summary(fit, test="Wilks")but I get p values for intercept and regression coefficient as in anova() function, not for the hull model.

multivariate regression
How can I run multivariate linear regression in R (I have got 3 dependent variables and only 1 independent variable)? I tried lm function, but it gave different R2 and p values for every dependent variable. I need one R2 and p value for the model.

I'm not seeing any outbound IPv6 traffic from my CentOS 7 box on the WAN

stacking consecutive columns
I have a file, each column of which is a separate year, and each row of each column is mean precipitation for that month. Looks like this (except it goes back to 1964).
