Producing a table with mean values
Hi All,
I have a data set wit three size classes (pico, nano and micro) and 12
different sites (Seamounts). I want to produce a table with the mean and
standard deviation values for each site.

PCA legend outside of PCA plot
Hi All,
I have been trying to get to plot my PCA legend outside of the PCA plot,
but success still alludes me.
Can you guys please advise how I can achieve this. I used locater() to
obtain coordinates for below the Comp.1 axis. Using these coordinates the
legend disappears.
Below is the code for the PCA and legend.
Thanks in advance for the help.

plotting multiple variables in 1 bar graph
I'd greatly appreciate your help in making a bar graph with multiple
variables plotted on it. All the help sites I've seen so far only plot 1
variable on the y-axis
Data set:
I have 6 sites, each measured 5 times over the past year. During each
sampling time, I counted the occurrences of different benthic components

Coral with Xen
Hi!
Coral isn''t working from Xen. If you can please try it, maybe i''m just
doing something wrong. However it works from outside Xen with the same
setup.
Can Xen cause this kind of DNS errors?
Try something like: http://www.scs.cs.nyu.edu.nyud.net:8090/coral/
or http://www.google.com.nyud.net:8090/

which multivariate regression?
Hi R-Users,
I have a student doing work with lionfish and she has been trying to analyse
a multivariate dataset to see what variables/factors are influencing the
behaviour of lionfish. We have attempted a number of analyses, including
rpart, relimpo and standard linear regression but we are not having much
luck with quality output. The data is very non-normal and we would
appreciate some advice

Xen Starting DomainU:Error: Device 0 (vif) could not be connected. Hotplug scripts not working
hi,
I am trying to start a new domainU but got the error:
Error: Device 0 (vif) could not be connected. Hotplug scripts not working
I have struggled with it for a long time. I found somebody else report this
but can not find a solution.
The xen version is xen-3.0 latest version.
I do not have a initrd.
Domain0 works fine but when I create a new domain, it always gives an error
as above.
Thanks,

Species accumulation curves with differential sampling effort
Hello! I'm a PhD student working with coral reef fish diversity in Mexico.
I want to do species accumulation curves but I have differential sampling
effort for each "sample".
Do you know or have developed an R script that consider the differential
effort of each sample?
PRIMER and other programs use each pack of species as a replica without the
possibility of telling the program that

Goodness-of-fit test for gamma distribution?
Hi all,
I am wondering if anyone has written (or knows of) a function that
will conduct a goodness-of-fit test for a gamma distribution. I am
especially interested in test statistics have some asymptotic
parametric distribution that is independent of sample size or values
of fitted parameters (e.g., a chi-squared distribution with some
fixed df), because I want to fit gamma distributions to

how to assign a group mean to individual cases?
I need advice on how to create a variable that is the group mean of
another variable.
For example, I have a variable called x for which each row in the data
set has a value. I also have a nominal variable called g that
indicates which of 100 different groups each row belongs to.
So, I want to create a new variable called w, which is the group mean
of x for which ever group the row belongs to (as

group mean, minus each row's value
I used the following to assign each row the group average, where w is
the new group average variable, x is the variabale to be averaged, and
g is the nominal group indicator:
w <- ave(x,g)
Now I want to calculate the group average, but WITHOUT each row's
value of x. Is there an easy way to do this? I'm sure I'm missing
something obvious here, but for the life of me I can't

"symbol print-name too long"
All,
I've coded a function and it works manually if I copy it line by line into R.
However, when I try to "load" (copy and paste) the entire function into
R, I get the following error after the listed line of code:

Does anyone you know what this error means? Strangely, when I copy the

Samba4 Winbind on DC Authentication problem
So, I've finally gotten around to installing a Samba4 AD DC. I've
joined a Win7 and Ubuntu machine to the domain so far, and all works
perfectly. Great job guys, it's nice to see this functionality working
solidly on Samba!
The problem is coming in on the actual DC host. My Ubuntu laptop is
running winbindd 3.6.18, and as I said, all went flawlessly. The DC

Problem with a if statement inside a function
I have a really long functions, and at the end of the function, I am using a
if statement
to tag certain keywords based on whether they have certain values contained

However, the if statement doesn't seem to work.
When I had split up the commands into various functions, it worked fine, but

Dear R list,
I have a sequence of weekly observations of number of adults and larvae

subtropical area with pronounced wet and dry seasons. Wet and dry
seasons are each defined 26 weeks long with fixed start and end dates.
The data span 103 weeks (two seasons each of wet and dry) with some
missing weeks. What I would like to do is
