R-alpha: inconsistency R/Splus of sample()

[Friedrich Leisch]

The function sample has different behaviour under R and Splus when
called with zero sample size:

R> x<-rnorm(10)
R> sample(x,0)
Error in sample(length(x), size, replace) : invalid second argument

Splus> x<-rnorm(10)
Splus> sample(x,0)
numeric(0)


IMO the Splus behaviour makes more sense, because it returns the
requested `sample' of size 0.
