pretty_range: Create a pretty sequence over a range of a vector

Description

Creates an evenly spaced, pretty sequence of numbers for a range of a vector.

Usage

pretty_range(x, n = NULL, length = NULL)

Arguments

x

A numeric vector.

n

Numeric value, indicating the size of how many values are used to create a pretty sequence. If x has a large value range (> 100), n could be something between 1 to 5. If x has a rather small amount of unique values, n could be something between 10 to 20. If n = NULL, pretty_range() automatically tries to find a pretty sequence.

length

Integer value, as alternative to n, defines the number of intervals to be returned.

Value

A numeric vector with a range corresponding to the minimum and maximum values of x.

Examples

# NOT RUN {
library(sjmisc)
data(efc)

x <- std(efc$c12hour)
x
# pretty range for vectors with decimal points
pretty_range(x)

# pretty range for large range, increasing by 50
pretty_range(1:1000)

# increasing by 20
pretty_range(1:1000, n = 7)

# return 10 intervals
pretty_range(1:1000, length = 10)

# same result
pretty_range(1:1000, n = 2.5)

# }
