R Error in names() – attribute must be same length as vector (2 Examples)

This article shows how to avoid the “Error in names() : ‘names’ attribute must be the same length as the vector” in R programming.

Creating Example Data

x <- c(4, 1, 7, 6, 4)              # Create vector in R
x                                  # Show example vector in RStudio
# [1] 4 1 7 6 4
nms <- LETTERS[1:7]                # Define names in R
nms                                # Show names in RStudio
# [1] "A" "B" "C" "D" "E" "F" "G"

Example 1: Replicating the Error in names() : attribute must be same length as vector

names(x) <- nms                    # Trying to apply names() function
# Error in names(x) <- nms : 
#   'names' attribute [7] must be the same length as the vector [5]

Example 2: Solving the Error in names() : attribute must be same length as vector

nms_new <- nms[1:length(x)]        # Harmonize length of vector and names
names(x) <- nms_new                # Properly applying names() function
x                                  # Show updated vector in RStudio
# A B C D E 
# 4 1 7 6 4
