R Warning Message – Removed rows containing non-finite values (stat_bin) (2 Examples)

In this tutorial, I’ll explain how to deal with the “Warning message: Removed X rows containing non-finite values (stat_bin)” in the R programming language.

Preparing the Examples

data(iris)                         # 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 & load ggplot2
library("ggplot2")

Example 1: Replicating the Warning – Removed X rows containing non-finite values (stat_bin)

ggplot(iris,                       # Specifying xlim leads to warning
       aes(x = Sepal.Length)) +
  geom_histogram() +
  xlim(4, 7)
# Warning messages:
# 1: Removed 12 rows containing non-finite values (stat_bin). 
# 2: Removed 2 rows containing missing values (geom_bar).

Example 2: Fixing the Warning – Removed X rows containing non-finite values (stat_bin)

ggplot(iris,                       # Do not specify xlim function
       aes(x = Sepal.Length)) +    # Draw ggplot plot with manual xlim
  geom_histogram()
