RE: q function in distr package [ Reply ]

This has been answered off list Jan 21 2016; for completeness, I am filling my answer from Jan 2016 to this forum:

Hi Laurie,

usage of our accessor q() for arguments of class distribution is a bit of a problem in RStudio, because they catch calls to q() and treat them separately. I talked to them in this issue, but they refused to allow to overload q() as a method [which per se is allowed in R], so we cannot do much about this.

That said, distr::q should work --- try this:

require(distr)
N <- Norm()
distr::q(N)(0.4)
##
## and for distr-2.6
# q.l(N)(0.4)

In addition, from distr-2.6 onward, there are synonyma p.r and q.l for accessors p, q for slots p and q of distributions.

p.r and q.l are to complement the left [right] continuous variants p.l and q.r, which have been there for a while --- you might know that p and q always have been the right [left] continuous variants as is standard in most textbooks nowadays, so names p.r and q.l are just a little more specific than their still valid synonyma p and q, and, in addition, will not cause problems in RStudio.

I hope this helps,
best regards,
Peter

q function in distr package [ Reply ] By: Laurie Berrie on 2016-01-21 10:48	[forum:45466]
Hi there, I am having some issues using the q function in distr as this is also used to quit R. I was wondering if there is a work around to this. I have tried using distr:: to specify the package and embedding it in another function but neither of these have proved successful. Any help would be greatly appreciated. Many thanks, Laurie
