Transpose Data Matrix & Maintain First Variable as Column Names in R (Example Code)

In this tutorial, I’ll illustrate how to transpose a data set and use the first variable as column names in the R programming language.

Introduction of Example Data

my_df <- data.frame(v1 = paste0("col", 1:5),           # Example data
                    v2 = letters[1:5],
                    v3 = letters[6:10],
                    v4 = letters[11:15],
                    v5 = letters[16:20])
#     v1 v2 v3 v4 v5
# 1 col1  a  f  k  p
# 2 col2  b  g  l  q
# 3 col3  c  h  m  r
# 4 col4  d  i  n  s
# 5 col5  e  j  o  t

Example: Apply setNames & data.frame Functions to Transpose Data Frame & Keep First Column as Header

my_df_trans <- setNames(data.frame(t(my_df[ , - 1])),  # Transposing data
                        my_df[ , 1])
my_df_trans                                            # Display new data
#    col1 col2 col3 col4 col5
# v2    a    b    c    d    e
# v3    f    g    h    i    j
# v4    k    l    m    n    o
# v5    p    q    r    s    t
