Hello list,
I' trying to estimate a log likelihood function from my data.
I apply the mean to all my simulations, and I get something like this:
apply(likelihood, c(2, 3, 4), mean,na.rm=TRUE)
, , 1
[,1] [,2] [,3] [,4] [,5][,6]
[,7]
[1,] 0.73162327
Dear R list,
I want to aggregate the number of individuals 'IND' of the same ORDER,
within each site and season CAMP,TRANS... but I also want to keep record of
the habitat HAB and LOTE
For example I have this:
CAMP LOTE HAB TRANS IND ORDEN
1765 C1 B1 BB1 7 HEMIPTERA
ORTHOPTERA 2
18 C1 B1 BB3 ORTHOPTERA 1

Dear R list,
I'm attaching a sample of my data which consists on the presence/absence

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!
Sure! Although I'm not sure how to use dput()
Here is more detail and some data what I want is that the repetitions
in Y (at the end) only have 1 or 0...

Hi Andrea
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
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
I know this seems like a very easy question (and maye it is) but I've been
trying to simulate nested data and been unsucessful so far..
I want to simulate a varying number of species within a group; and then
create an array to store the results of my for-loop. For example:
groups-3

I want to simulate a varying number of species within a group
the R
object species. Thus, I changed the name of that R object to
speciesgroups and altered your code so that it runs by removing the
erroneous c().
Did you try my suggestion, and did or did it not help your problem?
