geometric.sequence: Create a Geometric Sequence

Description

Create a geometric sequence.

Usage

GeometricSequence(length, initial.value = 1, discount.factor = .5)

Arguments

length

A positive integer giving the length of the desired sequence.

initial.value

The first term in the sequence. Cannot be zero.

discount.factor

The ratio between a sequence term and the preceding term. Cannot be zero.

Value

A numeric vector containing the desired sequence.

Examples

# NOT RUN {
GeometricSequence(4, .8, .6)
# [1] 0.8000 0.4800 0.2880 0.1728

GeometricSequence(5, 2, 3)
# [1]   2   6  18  54 162

# }
# NOT RUN {
GeometricSequence(0, -1, -2)
# Error: length > 0 is not TRUE
# }
