Convert List of Vectors to Data Frame in R (2 Examples)


This tutorial explains how to convert a list of vectors to a data frame in the R programming language.

Let’s get started!


Creating Example Data

In the following examples, we will use this example list:

my_list <- list(A = 1:5, B = letters[1:5])   # Create example list
# $A
# [1] 1 2 3 4 5
# $B
# [1] "a" "b" "c" "d" "e"

As you can see based on the output of the RStudio console, our example list contains two vectors. One of them is numeric and one of them is a character.


Example 1: Convert List to Data Frame Columns

If we want to convert each of the two list elements to a column, we can use a combinations of the cbind,, and R functions:, my_list))       # Convert list to data frame columns
#   A B
# 1 1 a
# 2 2 b
# 3 3 c
# 4 4 d
# 5 5 e

You can see based on the RStudio console output that each of our list elements was converted to a column.

Note that the list elements need to have the same length.


Example 2: Convert List to Data Frame Rows

We can also use the rbind function instead of cbind in order to convert our example list to a data frame with two rows and five columns (i.e. each value of our list elements is stored in a new column):, my_list))       # Convert list to data frame rows
#   V1 V2 V3 V4 V5
# A  1  2  3  4  5
# B  a  b  c  d  e
