Provide a way to turn off error output in bpser

[limwz01]

I always get the below error when running many different pbeta and I am fine with it underflowing. Can this error be turned off? In fact, it is not even printing a proper error line as the newline is missing.

pbeta(*, log.p=TRUE) -> bpser(a=198241, b=35.5558, x=0.97982,...) underflow to -Inf
