Calculate a mean for several months for several years
Hello everyone,
I have a dataset with 3 colums (Year, Month, MeanTemp). Now I would like to
calculate the average of the mean temperature for the summer months (Juli,
August, September) for each of the 20 years.
I'm sure it's somehow possible with a loop, but all I tried so far didn't
worked and by the time I spent looking for a solution I would have even be
faster doing this in

function logit() vs logistic regression
Hello!
When I am analyzing proportion data, I usually apply logistic regression
using a glm model with binomial family. For example:
m <- glm( cbind("not realized", "realized") ~ v1 + v2 , family="binomial")
However, sometimes I don't have the number of cases (realized, not
realized), but only the proportion and thus cannot compute the binomial
model. I just

Date format in plot
Hello, I plot the abundance of a species in relation to the date. To have the
date as a continous variable I put it in the format "standard" in excel
(f.ex. 39939 means 06.05.2009). R uses 39939 on the x axis, but I would like
to have "06.05". I tried to use as.Date as suggested in some discussion but
I don't manage to use it, the returned date is not correct. Do you have

Mantel test
Hello! It is not really linked to R, but can somebody explain me why we
sometimes make a mantel test directly for to distance matrices and sometimes
we first make a gradient analysis and then a mantel test between the axis?
Thank you

Represent point size according to frequency
Hello! I would like to make a scatterplot of my data, but the problem is that
several points have the same x and y values and are represented as only one
point. I wonder if there is a way to represent the data points, but with
point size representing the frequency of the depicted x-y value?
Thank you!

Mantel test least square line
Hello, I performed a Mantel test and plotted communitiy similarities. I
would like to add a least square line. I thought about using abline taking
as slope the r-statistic of the Mantel test and calculating the y-intercept
analytically. Is this method correct? Is there any function for this
calculation? Thank you

Plot several graphs in the same window
Hello, I would like to plot a large number of graphs (43) in a same window. I
tried wit par(mfrow=c(8,5)), but when I give the code for the plots I
receive a error message saying that the margins are to wide. Can someone
help me? Is it possible to put so many graphs in a single window? Thank you

Exclude 0 values from plot
Hello, I have a matrix of species abundance with a lot of 0 values. I would
like to plot the species abundance vs date, but I don't want that the 0
values appear as points on my graph. Do you know how I could represent only
non-0 values? Thank you very much

Confusion metaMDS and CA
Hello, I read a lot about ordination, but I am still confused... I have data
on species presence/absence for 8 different sites and I would like to
represent my species and the sites on an ordination plot to see if some
species are associated with specific sites. I used metaMDS function, which
displays both sites and species and it seems to work well. However why are
most people using CA instead of

Problem with lmer and fixef
Hello,
I am trying to do contrasts after applying a binomial mixed effect model
with the function lmer. I have to extract the fix effect values, but as I
write fixef(model), I get this error message:
Error in UseMethod("fixef") :
no method for 'fixef' with objects of class "mer"
Has anybody some ideas why? And how can I then post-hoc testing my data if I
cannot do

Assessing overdispersion and using quasi model with lmer, possible?
Hello!
I am trying to model data on species abundance (count data) with a poisson
error distribution. I have a fixed and a random variables and thus needs a
mixed model. I strongly doubt that my model is overdispersed but I don't
know how to get the overdispersion parameter in a mixed model. Maybe someone
can help me on this point. Secondly, it seems that quasi models cannot be
implemented

Since harmonics are often accompanied by a temperature rise, thermography can be used to detect evidence of their presence.

upsmon/upssched on ups temperature
Hi All,
I was wondering what people are doing to shutdown their equipment based
on the temperature NUT grabs from a UPS? It doesn't appear that
upsmon(8) has an appropriate notify event for temperature levels.
For the time being, it looks like I'll write a simple perl wrapper
around upsc to get ups.temperature, but would love to use something
natively from NUT, if possible.
Also,

Monitoring hardware in Domain-0 - core temperature specifically
Hi,
I got a bright idea to monitor CPU core temperature using ''lm_sensors''.
I was testing on my quad-core desktop machine and everything seemed great.
However - my Domain-0 has just two VCPU''s assigned to it and this is
exactly what ''sensors'' report.
Any ideas about how to work around that besides letting Domain-0 use all
CPUs?
Regards, Danilo

GPU Temperature?
-----BEGIN PGP SIGNED MESSAGE-----

Hi there,
I just wondered if there is an open-source way of getting information
about the temperatures provided by the internal sensors. I've read that
nvclock is providing such information but only if the binary driver is
installed and used.
When I run 'sensors-detect' is see three adapters provided through nouveau:
