Error in .subset(x, j) : invalid subscript type ‘list’ (2 Examples)
In this tutorial, I’ll illustrate how to solve the Error in .subset(x, j) : invalid subscript type ‘list’ in the R programming language.
Creating Example Data
data(iris) # Loading example data frame head(iris) # Printing data frame to RStudio console # 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 |
data(iris) # Loading example data frame head(iris) # Printing data frame to RStudio console # 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
Example 1: Replicating the Error in .subset(x, j) : invalid subscript type ‘list’
iris[ , list("Sepal.Length", "Species")] # Try to select variables with list # Error in .subset(x, j) : invalid subscript type 'list' |
iris[ , list("Sepal.Length", "Species")] # Try to select variables with list # Error in .subset(x, j) : invalid subscript type 'list'
Example 2: Solve the Error in .subset(x, j) : invalid subscript type ‘list’
iris_sub <- iris[ , c("Sepal.Length", "Species")] # Properly select variables with vector head(iris_sub) # Display data frame subset # Sepal.Length Species # 1 5.1 setosa # 2 4.9 setosa # 3 4.7 setosa # 4 4.6 setosa # 5 5.0 setosa # 6 5.4 setosa |
iris_sub <- iris[ , c("Sepal.Length", "Species")] # Properly select variables with vector head(iris_sub) # Display data frame subset # Sepal.Length Species # 1 5.1 setosa # 2 4.9 setosa # 3 4.7 setosa # 4 4.6 setosa # 5 5.0 setosa # 6 5.4 setosa
