How to Plot a Function Curve in R Programming (2 Examples)

manual_function <- function(values) {                 # User-defined function
  values^3 - values^2 + values * 50
}

manual_function <- function(values) { # User-defined function values^3 - values^2 + values * 50 }

curve(manual_function,                                # Using curve function
      from = - 10000,
      to = 10000)

curve(manual_function, # Using curve function from = - 10000, to = 10000)

ggplot_data <- data.frame(range = c(- 10000, 10000))  # Data frame for ggplot2 plot

ggplot_data <- data.frame(range = c(- 10000, 10000)) # Data frame for ggplot2 plot

install.packages("ggplot2")                           # Install ggplot2 package
library("ggplot2")                                    # Load ggplot2 package

install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 package

ggplot(ggplot_data, aes(range)) +                     # Using ggplot2 package
  stat_function(fun = manual_function)

ggplot(ggplot_data, aes(range)) + # Using ggplot2 package stat_function(fun = manual_function)
