You can use the **xlim()** and **ylim()** functions to set the x-axis limits and y-axis limits of plots in R.

The following examples show how to use these functions in practice.

**Example 1: Use xlim() to Set X-Axis Limits**

The following code shows how to create a scatterplot in R and specify the x-axis limits using the **xlim()** function:

#define data frame df <- data.frame(x=c(1, 3, 4, 5, 7, 9), y=c(7, 7, 8, 12, 15, 19)) #create scatterplot with x-axis limits ranging from 0 to 20 plot(df$x, df$y, pch=19, xlim=c(0, 20))

**Example 2: Use ylim() to Set Y-Axis Limits**

The following code shows how to create a scatterplot in R and specify the y-axis limits using the **ylim()** function:

#define data frame df <- data.frame(x=c(1, 3, 4, 5, 7, 9), y=c(7, 7, 8, 12, 15, 19)) #create scatterplot with y-axis limits ranging from 0 to 30 plot(df$x, df$y, pch=19, ylim=c(0, 30))

**Example 3: Use xlim() & ylim() to Set Axis Limits**

The following code shows how to create a scatterplot in R and specify both the x-axis limits and the y-axis limits:

#define data frame df <- data.frame(x=c(1, 3, 4, 5, 7, 9), y=c(7, 7, 8, 12, 15, 19)) #create scatterplot and specify both x-axis limits and y-axis limits plot(df$x, df$y, pch=19, xlim=c(0, 20), ylim=c(0, 30))
