You can use the following methods to plot a function curve in R:

**Method 1: Use Base R**

curve(x^3, from=1, to=50, xlab='x', ylab='y')

**Method 2: Use ggplot2**

library(ggplot2) df <- data.frame(x=c(1, 100)) eq = function(x){x^3} #plot curve in ggplot2 ggplot(data=df, aes(x=x)) + stat_function(fun=eq)

Both methods will produce a plot that shows the curve of the function **y = x ^{3}**.

The following examples show how to use each method in practice.

**Example 1: Plot Function Curve Using Base R**

The following code shows how to plot the curve of the function **y = x ^{3}** using the

**curve()**function from base R:

#plot curve using x-axis range of 1 to 50 curve(x^3, from=1, to=50, xlab='x', ylab='y')

Note that you can use the following arguments to modify the appearance of the curve:

**lwd**: Line width**col**: Line color**lty**: Line style

The following code shows how to use these arguments in practice:

#plot curve using x-axis range of 1 to 50 curve(x^3, from=1, to=50, xlab='x', ylab='y', lwd=3, col='red', lty='dashed'))

Feel free to play around with the values for these arguments to create the exact curve you’d like.

**Example 2: Plot Function Curve Using ggplot2**

The following code shows how to plot the curve of the function **y = x ^{3}** using the

**stat_function()**function from ggplot2:

library(ggplot2) #define data frame df <- data.frame(x=c(1, 100)) #define function eq = function(x){x^3} #plot curve in ggplot2 ggplot(data=df, aes(x=x)) + stat_function(fun=eq)

You can also use the **lwd**, **col**, and **lty** functions within the **stat_function()** function to modify the appearance of the curve:

library(ggplot2) #define data frame df <- data.frame(x=c(1, 100)) #define function eq = function(x){x^3} #plot curve in ggplot2 with custom appearance ggplot(data=df, aes(x=x)) + stat_function(fun=eq, lwd=2, col='red', lty='dashed')

**Note**: You can find the complete documentation for the ggplot2 **stat_function()** function here.
