How to Make a Data Frame with Column Names in R (2 Examples)
On this page, I’ll demonstrate how to make a data frame with column names in the R programming language.
Example 1: Constructing a Data Frame with Column Names & Values
df_A <- data.frame(col1 = 1:6, # Data frame with values col2 = "yyy", col3 = LETTERS[10:15], col4 = 55) df_A # col1 col2 col3 col4 # 1 1 yyy J 55 # 2 2 yyy K 55 # 3 3 yyy L 55 # 4 4 yyy M 55 # 5 5 yyy N 55 # 6 6 yyy O 55 |
df_A <- data.frame(col1 = 1:6, # Data frame with values col2 = "yyy", col3 = LETTERS[10:15], col4 = 55) df_A # col1 col2 col3 col4 # 1 1 yyy J 55 # 2 2 yyy K 55 # 3 3 yyy L 55 # 4 4 yyy M 55 # 5 5 yyy N 55 # 6 6 yyy O 55
Example 2: Constructing an Empty Data Frame with Column Names
df_B <- data.frame(col1 = numeric(), # Data frame without values col2 = factor(), col3 = integer(), col4 = character()) df_B # [1] col1 col2 col3 col4 # <0 rows> (or 0-length row.names) |
df_B <- data.frame(col1 = numeric(), # Data frame without values col2 = factor(), col3 = integer(), col4 = character()) df_B # [1] col1 col2 col3 col4 # <0 rows> (or 0-length row.names)
