Dear R Development Core Team,

I would like to submit a bug in pbeta and, consequently, in  pf.
The function -pbeta(x,.5,2047,lower.tail=F,log.p=T) increases
roughly linearly in [.27, .292], next it is equal to Inf in [.293,.299] and
in [.3,.32] it increases linearly again. Please check:

Best regards,

Piotr Pokarowski
