How to use ifelse without invoking warnings

p <- .05
k <- c(-1.2,-0.5, 1.5, 10.4)
n <- 10

ans <- ifelse (k >= -1 & k <= n, pbeta(p,k+1,n-k,lower.tail=FALSE),

suppressWarnings(ans <- ifelse (k >= -1 & k <= n,

Hi,
I would like to execute the following vectorized calculation:

  ans <- ifelse (k >= -1 & k <= n, pbeta(p, k+1, n-k, lower.tail = FALSE),
ifelse (k < -1, 0, 1) )

For example:

k <- c(-1.2,-0.5, 1.5, 10.4)
n <- 10
ans <- ifelse (k >= -1 & k <= n, pbeta(p,k+1,n-k,lower.tail=FALSE),

ifelse (k < -1, 0, 1) )
Warning message:
In pbeta(p, k + 1, n - k, lower.tail = FALSE) : NaNs produced

print(ans)

[1] 0.000000000 0.006821826 0.254991551 1.000000000

The answer is correct.  However, I would like to eliminate the annoying
warnings.  Is there a better way to do this?

Thank you,
Ravi

?suppressWarnings

p <- .05
k <- c(-1.2,-0.5, 1.5, 10.4)
n <- 10

ans <- ifelse (k >= -1 & k <= n, pbeta(p,k+1,n-k,lower.tail=FALSE),

ifelse (k < -1, 0, 1) )
Warning message:
In pbeta(p, k + 1, n - k, lower.tail = FALSE) : NaNs produced

suppressWarnings(ans <- ifelse (k >= -1 & k <= n,

pbeta(p,k+1,n-k,lower.tail=FALSE), ifelse (k < -1, 0, 1) ))
## no warnings
