[Rd] vector passed to `if' in `pgamma'

[Roger Peng]

In the current R-devel sources, the `pgamma' function gives a warning when
the `shape' argument is passed as a vector of length > 1.  That is,

> pgamma(3, 1)
[1] 0.950213
> pgamma(3, c(1, 2))
[1] 0.9502129 0.8008517
Warning message: 
the condition has length > 1 and only the first element will be used in:
if (shape <= 0) stop("shape must be strictly positive") 

Maybe something like

if(identical(any(shape <= 0), TRUE))
  ....

?
