F-Tests in generalized linear mixed models (GLMM)
...anyone konw why, or how to fix the problem? To illustrate the
problem, I send the output of a simulated example.
Thank you very much in advance.
Best regards, Bj?rn
Example:
> # simulation of data
> n <- 300
> x1 <- sample(c(T,F), n, replace=TRUE)
> x2 <- rnorm(n)
> random1 <- sample(c("level1","level2","level3"), n, replace=TRUE)
> true.lp <- 5 + 1.1*x1 + 0.16 * x2
> mu <- exp(true.lp)
> sigma <- mu * 1
> a <- mu^2/sigma^2
> s <- sigma^2/mu
> y <- rgamma(n, shape=a, scale=s)

random sample from arrays
...-sample(x,50)
print(c(i,"->", set), quote = FALSE)
}
which basically do the trick, but I just can't save the results outside the
loop.
After having the random sets of lines it wasn't a problem to extract the
line from the arrays using subset.
genSet1 <-sample(x,50)
random1 <- genes %in% genSet1
subsetGenelist <- subset(genelist, random1)
is there a different way of creating these random vectors or saving the loop
results outside tjhe loop so I cn work with them?
Thanks a lot

Save Venn-diagram (Vennerable) together with table and plot in single pdf page

Random resampling of columns in species association matrices
I have a host-parasite association matrix in which parasite species are rows
and host species columns and cells contain the frequency of interactions.
Some parasites are associated with many hosts, and some hosts harbor several
parasites, and I want to repeatedly select only one single representative
host per "generalized" (multi-host) parasite to create a new matrix in which
no hosts

Choosing a random number between x and y
Hi,
Ive been trying to find a function that will allow me to pull out a number
between a minimum and maximum threshold.
I want a random decimal number between, for example, 0 and 0.5 or 0 and 0.7.
I've been searching everywhere for a function that will allow me to do this
in R, but I have yet to be successful. Any help would be much appreciated.
Thanks in advance
