Listing elements of a 4D array
Dear list,
I'm having trouble to see how my elements on a 4 dimensional array are
listed.
For example, I generated the following array:
junk.melt=melt(occ.data,id.var=c("Especie", "Site", "Rep", "Año"),
measure.var="Pres")
y=cast(junk.melt, Site ~ Rep ~ Especie ~ Año)
Now, I want to be able to look at how my species (Especie) are listed, in

help "reshaping" dataframe
List,
I want to reshape my data, but I'm not sure how to do it... it might be a
simple task, but don't know which package does this.
"occ.data" (see below) is how my original data are arranged, and I know
that with melt() I can reshape it like "y" (see below). However, I just
want to build a matrix like the "y" matrix, but with only 2 dimensions.

Changing frequency values to 1 and 0
Dear list,
I'm working with a large data set, where I grouped several species in one
group (guild). Then I reshaped my data as shown below. Now, I just want to
have "Rep" only as 1 or 0.
I'm not being able to change the values of rep>=1 to 1... tried many things
and I'm not being successful!

Como imponer una matriz de correlaciones en un modelo mixto?
Hola, mi pregunta es la siguiente:
Tengo un modelo genético aditivo, donde los individuos estan emparentados.
Quiero que la matriz de parentesco sea la matriz de coeficientes de las
correlaciones entre genotipos. En SAS, con PROC MIxed podia agregarla como
un archivo y usarla en la sentencia random...No encuentro como hacerlo en R,
alguna idea??

lme fitted correlation of random effects: where is it?
The print method for lme *prints out* the fitted correlation matrix for
the random effects. Is there any way to get these values as an object in
R? I have examined the components of the lme object (called "junk" in the
example below) and the components of summary(junk) without finding these
numbers.
(How I did this: I dumped the entire lme object to a text file and then

testing diff for slopes and intercepts
I fit the model
fit<-lm(thresh~cond*Ne)
where
thresh is the reponse
cond is a factor with levels a, b, and c
Ne is a continuous indep var
I think of this full model as having three lines: thresh as a function of
Ne for each condition. Thus we have slopea, slopeb, slopec, inta, intb,
intc.

Linux box to do routing and load sharing for the 3 connections. A
fourth interface is connected to the LAN with private IP addresses.
Am using iptables to SNAT traffic to the appropriate IP depending on

Cannot get Centrino N 6200 wireless NIC to work Cento 6.4
I installed Centos 6.4 on my laptop and neither of the network interfaces
will work. When I boot up to windows both the wired and the wireless
network interfaces work. I have attached dmesg output for the wireless
card. Reading through the messages it appears that OS cannot talk to the
NIC.
