Generate numeric sequence from range of a vector

Source: R/signif_trailing.R
seq_range.Rd

Creates a numeric sequence spanning the range of input data with specified step size and direction. Optionally rounds the range endpoints before generating the sequence.

Usage

seq_range(x, by = 1, direction = c("up", "down"), digits = NA)

Arguments

x

A numeric vector.

by

A numeric step size for the sequence. Default is 1.

direction

A character string specifying sequence direction. Either "up" (the default) for ascending or "down" for descending sequence.

digits

An integer specifying number of decimal places to round range endpoints, or NA (the default) for no rounding.

Value

A numeric vector spanning the range of the input data.

Details

The output vector will likely be a different length than the input vector.

The function:

  • Calculates the range of x (ignoring NA values).

  • Optionally rounds the range endpoints if digits is specified.

  • Generates a sequence with the specified step size.

  • Reverses the sequence if direction = "down".
