Expand Axis Limits for Plots

Calculates axis limits for a plot that are aligned with pretty breaks, ensuring that all data points are within the range and the maximum value is comfortably included, in accordance with RIVM styling. Optionally, the lower limit can be set to zero.

Usage

ro_gg_axis(x, start_at_zero = TRUE)

Arguments

x

Numeric vector of values to be plotted.

start_at_zero

Logical; if TRUE (default), the lower limit of the axis will start at 0.

Value

A numeric vector of length 2, giving the minimum and maximum axis limits.
