unif: Nice Uniform Points in Interval

Description

Give regularly spaced points on interval $[-c,c]$ with mean 0 (exactly) and variance about 1 (very close for even n and larger round.dig). Note that $c$ depends on n.

Usage

unif(n, round.dig = 1 + trunc(log10(n)))

Arguments

n

positive integer specifying the number of points desired.

round.dig

integer indicating to how many digits the result is rounded.

Value

• numeric vector of length n, symmetric around {0}, hence with exact mean 0, and variance approximately 1.

See Also

runif for producing uniform random numbers.

Examples

(u <- unif(8))
var(u)

(u. <- unif(8, 12))# more digits in result, hence precision for Var :
var(u.)
