I've got Fedora 31.
I just checked, and R 3.6.2 is available now.
Progress...

Um, n(n-1)(n-2)...(n-k+1)/factorial(k), of course, but I think the argument
still holds.
Also, note that there are overflow conditions involved with computing
n(n-1)(n-2)...(n-k+1)/factorial(k)
as written, so it is computed in a loop with alternating multiply and divide
steps. This introduc
That crossed my mind too, but presumably someone designed choose() to handle
the near-integer cases specially. Otherwise, we already have beta() -- you just
need to remember what the connection is ;-).
I would expect that it has to do with the binomial and negative binomial
distributions, but

And while everyone is talking about operating systems...

At the risk of throwing oil on a fire. If we are talking about fractional
values of choose() doesn't it make sense to look to the gamma function for the
correct analytic continuation? In particular k<0 may not imply the function
should evaluate to zero until we get k<=-1.
Example:
``` r

Hi all,
I maintain the package �qrandom� which is based on a web API. In last time

I implemented the following code in v1.2.2 to ensure that tests are only run
if the website is accessible and to avoid the CRAN checks to fail:

Hi,
During my recent r2sundials development, I've came across a strange test
failing during 'R CMD check' exclusively on win R-devel which I could
reproduce with a minimal example that I present here.
The toy packages testarma1 [1] and testarma2 [2] are minimal
modifications of a skeleton pack
