# get_breaks: Easy Break Creation for Numeric Axes In ggpubr: 'ggplot2' Based Publication Ready Plots

## Description

Creates breaks for numeric axes to be used in the functions `scale_x_continuous()` and `scale_y_continuous()`. Can be used to increase the number of x and y ticks by specifying the option `n`. It's also possible to control axis breaks by specifying a step between ticks. For example, if `by = 5`, a tick mark is shown on every 5.

## Usage

 `1` ```get_breaks(n = NULL, by = NULL, from = NULL, to = NULL) ```

## Arguments

 `n` number of breaks. `by` number: the step between breaks. `from` the starting value of breaks. By default, 0 is used for positive variables `to` the end values of breaks. This corresponds generally to the maximum limit of the axis.

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27``` ```# Generate 5 breaks for a variable x get_breaks(n = 5)(x = 1:100) # Generate breaks using an increasing step get_breaks(by = 10)(x = 1:100) # Combine with ggplot scale_xx functions library(ggplot2) # Create a basic plot p <- ggscatter(mtcars, x = "wt", y = "mpg") p # Increase the number of ticks p + scale_x_continuous(breaks = get_breaks(n = 10)) + scale_y_continuous(breaks = get_breaks(n = 10)) # Set ticks according to a specific step, starting from 0 p + scale_x_continuous( breaks = get_breaks(by = 1.5, from = 0), limits = c(0, 6) ) + scale_y_continuous( breaks = get_breaks(by = 10, from = 0), limits = c(0, 40) ) ```
