R Warning: argument is not numeric or logical (2 Examples)
In this article you’ll learn how to deal with the warning “argument is not numeric or logical: returning NA” in the R programming language.
Example Data
data(iris) # Loading some example data iris_num <- iris[ , 1:4] head(iris_num) # Sepal.Length Sepal.Width Petal.Length Petal.Width # 1 5.1 3.5 1.4 0.2 # 2 4.9 3.0 1.4 0.2 # 3 4.7 3.2 1.3 0.2 # 4 4.6 3.1 1.5 0.2 # 5 5.0 3.6 1.4 0.2 # 6 5.4 3.9 1.7 0.4 |
data(iris) # Loading some example data iris_num <- iris[ , 1:4] head(iris_num) # Sepal.Length Sepal.Width Petal.Length Petal.Width # 1 5.1 3.5 1.4 0.2 # 2 4.9 3.0 1.4 0.2 # 3 4.7 3.2 1.3 0.2 # 4 4.6 3.1 1.5 0.2 # 5 5.0 3.6 1.4 0.2 # 6 5.4 3.9 1.7 0.4
Example 1: Replicating the Warning – argument is not numeric or logical: returning NA
mean(iris_num) # Trying to apply mean function to data frame # [1] NA # Warning message: # In mean.default(iris_num) : # argument is not numeric or logical: returning NA |
mean(iris_num) # Trying to apply mean function to data frame # [1] NA # Warning message: # In mean.default(iris_num) : # argument is not numeric or logical: returning NA
Example 2: Solving the Warning – argument is not numeric or logical: returning NA
colMeans(iris_num) # Applying colMeans function to data frame # Sepal.Length Sepal.Width Petal.Length Petal.Width # 5.843333 3.057333 3.758000 1.199333 |
colMeans(iris_num) # Applying colMeans function to data frame # Sepal.Length Sepal.Width Petal.Length Petal.Width # 5.843333 3.057333 3.758000 1.199333
