pcbinom {Smisc} | R Documentation |
Uses the incomplete beta function to calculate a continuous version of the binomial cumulative distribution function.
pcbinom(x, n, p, lower.tail = TRUE, log.p = FALSE)
x |
Real valued vector of the number of successes. |
n |
Real valued vector, all elements in |
p |
Real valued vector, all elements in |
lower.tail |
logical; if |
log.p |
logical; if |
pcbinom
is equivalent to pbinom
for integer values of
n
and x
.
Note that pcbinom
does not recycle vectors in the usual fashion.
Each of the arguments x
, n
, and p
should have the same
length, or, one or more of them can have the same length, so long as the
other arguments have length 1. See examples below.
Returns a continuous version of the binomial distribution function.
This function was based on binom.c
in the R source code.
