The Uniform Distribution
Usage
dunif(x, min=0, max=1)
punif(q, min=0, max=1)
qunif(p, min=0, max=1)
runif(n, min=0, max=1)
Arguments
x,q
|
vector of quantiles.
|
p
|
vector of probabilities.
|
n
|
number of observations to generate.
|
min,max
|
lower and upper limits of the distribution.

Description
These functions provide information about the uniform distribution
on the interval from min to max. dunif gives the
density, punif gives the distribution function qunif
gives the quantile function and runif generates random
deviates.See Also
.Random.seed about random number generation,
rnorm, etc for other distributions.Examples
u <- runif(20)
all(punif(u) == u) # T
all(dunif(u) == 1) # T
var(runif(10000))#- ~ = 1/12 = .08333
all(runif(100, 2,2) == 2)#-> TRUE [exhibits bug in R version <= 0.63.1]
