Cauchy distribution limits
I have question (curiosity) regarding returned values of R's qcauchy
() function,
for nonexceedance probability (F). It seems the ideal returned range
of cauchy distribution should be [-Inf,Inf].
For F=0
> qcauchy(0)
[1] -Inf
but for F=1
> qcauchy(1)
[1] 8.16562e+15
It seems to me that the proper return value should be Inf???
For default (location=0,s...

qcauchy accuracy (PR#7902)
Full_Name: Morten Welinder
Version: 2.1.0
OS: src only
Submission from: (NULL) (216.223.241.212)
Now that pcauchy has been fixed, it is becoming clear that qcauchy suffers from
the same problems.
qcauchy(pcauchy(1e100,0,1,FALSE,TRUE),0,1,FALSE,TRUE)
should yield 1e100 back, but I get 1.633178e+16. The code below does much
better. Notes:
1. p need not be finite. -Inf is ok in the log_p case and R_Q_P01_check
already checks things.
2. No need to d...

bugs and misfeatures in polr(MASS).... fixed!
In polr.R the (several) functions gmin and fmin contain the code
> theta <- beta[pc + 1L:q]
> gamm <- c(-100, cumsum(c(theta[1L], exp(theta[-1L]))), 100)
That's bad. There's no reason to suppose beta[pc+1L] is larger than
-100 or that the cumulative sum is smaller than 100. For practical
datasets those assumptions are frequently violated, causing the

R-beta: Problem with `rpois'
There is a problem with `rpois'. It does seem to take care about the
order of the arguments. This is an example:
> rpois(n=1,lambda=2)
[1] 3
> rpois(lambda=2,n=1)
[1] 2 0
It obviously uses the first argument as the number of samples to be
drawn, which is wrong.
I used Version 0.49 Beta (April 23, 1997).
