Error in FUN(X[[i]], …) : object not found – ggplot2 geom_path in R (2 Examples)
In this article you’ll learn how to reproduce and debug the “Error in FUN(X[[i]], …) : object not found” in R programming.
Setting up the Examples
data(iris) # Loading example data head(iris) # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 3.5 1.4 0.2 setosa # 2 4.9 3.0 1.4 0.2 setosa # 3 4.7 3.2 1.3 0.2 setosa # 4 4.6 3.1 1.5 0.2 setosa # 5 5.0 3.6 1.4 0.2 setosa # 6 5.4 3.9 1.7 0.4 setosa |
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 |
my_plot <- ggplot(iris, # Drawing ggplot2 graphic aes(x = Sepal.Length, y = Sepal.Width, col = Species)) + geom_point() my_plot |

my_path <- data.frame(x = c(5, 7, 6, 7), # Setting parameters for path y = c(3, 4, 2, 3)) # x y # 1 5 3 # 2 7 4 # 3 6 2 # 4 7 3 my_path |
Example 1: Replicating the Error in FUN(X[[i]], …) : object not found
my_plot + # inherit.aes is set to TRUE geom_path(data = my_path, aes(x = x, y = y)) # Error in FUN(X[[i]], ...) : object 'Species' not found |
Example 2: Solving the Error in FUN(X[[i]], …) : object not found
my_plot + # inherit.aes is set to FALSE geom_path(data = my_path, aes(x = x, y = y), inherit.aes = FALSE) |
