cseq: Centered sequence generation

In the-mad-statter/washu: Helpful Functions for WashU Statistical Consultations

Centered sequence generation

Description

Generate regular sequences based on a central value

Usage

cseq(center, by, length.out = 3)

Arguments

center	the middle value of the sequence
by	number: decrement/increment of the sequence
length.out	desired length of the sequence

Details

Generates a sequence of numbers above and below a central value.

The length.out argument should be an odd integer. If the value given is fractional, it will be rounded up. If the value given is even, it will be made odd by adding one.

Value

vector of type integer or double

Examples

# integer center, integer by, odd length.out
cseq(center = 10, by = 2, length.out = 5)

# integer center, integer by, even length.out
# same as previous because even length.out is made odd by adding one
cseq(center = 10, by = 2, length.out = 4)

# double center, double by, odd length.out
# doubles also possible
cseq(center = 10.5, by = 2.25, length.out = 7)
