Thank you both for your advice! The z <- readLines(gzcon(url("
https://tcga.xenahubs.net/download/TCGA.GBMLGG.sampleMap/HumanMethylation450.gz";)),
) command worked out nicely

By the way, instead of saying only that there were warnings, it would be
nice to show some of them. E.g.,

")

These are gzipped files, I assume. So see ?gzfile and associated info
for how to open a gzip connection and read from it. You may also
prefer to search (e.g. at rseek.org) on "read a gzipped file" or
similar for possible alternatives.
Of course, if they're not gzipped files, then ignore the above.
Good evening,
I am attempting to load the following Xena dataset
https://tcga.xenahubs.net/download/TCGA.GBMLGG.sampleMap/HumanMethylation450.gz
I am trying to unpack the dataset and read it into R as a table, but due to
the size of the file, I am having some trouble. The following are the

Does fa function in psych package consider only complete cases when
missing=FALSE?
Why do I get slightly different results when I restrict my data to complete
cases compared to the whole data with the default missing=FALSE?

Dear Larry,
yes, because of various factors the r-cran-* packages from the stable and
especially the oldstable distribution are often not compatible with the
backported r-base packages provided on CRAN. At current, buster is not
affected, but your case shows that using stretch gives this proble

I don't know why I thought you wanted a *random* sequence..
The 'rep' function can do more than you realise.
generate_k <- function (N, n3) rep(1:3, c(n3+2, N-2-n3*2, n3))

Yes, you are right (and yours is one of the possible cases).
I think this works (I resorted to pen and paper for once)
generate_k <- function(N, n3){
n1 <- 2+n3
n2 <- N-n1-n3
out <- c(rep(1, n1), rep(2, n2), rep(3, n3))
return(out)
}
where N is the length of the sample, n3 is t
n_1 + ... + n_N = 2(N-1) is requested for integers n_i >= 1.
What about c(rep(2, N-2), 1, 1))?
but I'm afraid that this was not what you really wanted. ;-)
However, you didn't say if your sample should be random. :-)

Dear All,
I cannot unfortunately provide any R code, otherwise I would not need to post
this in the first place.
I need to generate a sample of N positive non-zero integers such that their
mean is *exactly* 2(N-1)/N, i.e. the mean depends on the length of the sample.
For a start, we can assume t
