[R] Generic distributions

[Matthias Kohl]

Hello Alberto, hello Greg,

in distr you can do:

library(distr)
N <- Norm(mean = 1, sd = 2)
p(N)(0.5)
r(N)(100)

!!! not: p(N, 0.5) or r(N, 100) !!!
A detailed description of package "distr" is given in package "distrDoc".

library(distrDoc)
vignette("distr")
