Method to obtain the cdf of an exponential
object.
# S3 method for exponential
cdf(x, ...)
The object to obtain the pdf of
Additional arguments (not used)
A function that computes the cdf of the exponential. Accepts as
input a vector t
at which to compute the cdf, an input rate
denoting the failure rate of the exponential distribution, and a
logical log
indicating whether to compute the log of the cdf.
By default, rate
is the failure rate of object x
.
