## How do I change the size of the axis labels in R?

**What is the scale of Y axis?**

(Default) A linear scale on the Y axis represents equal distance and change on a chart. So for example, if grid lines are enabled, a change of three spaces on a line graph may represent an increase of 3MB of data. Logarithmic. A logarithmic scale uses an equal distance and percentage change.

**How to set axis ticks for discrete and continuous axes in R?**

Set axis ticks for discrete and continuous axes. x or y axis can be discrete or continuous. In each of these two cases, the functions to be used for setting axis ticks are different. The functions scale_x_discrete() and scale_y_discrete() are used to customize discrete x and y axis, respectively.

## How can I customize the tick marks of each axis?

In addition to axes labels, the tick marks of each axis can be customized in different ways. The xaxp (X-axis) and yaxp (Y-axis) arguments allow customizing where the ticks of each axis start and end and the number of regions to divide the axis specifying vectors of the form c (start, end, number_regions).
