Learn R – How to Create Data Frame with Column Names

This article represents code in R programming language which could be used to create a data frame with column names. Please feel free to comment/suggest if I missed to mention one or more important points. Also, sorry for the typos.

Following are the key points described later in this article:

  • Create empty dataframe with column names
  • Create non-empty dataframe with column names

Create an Empty Dataframe with Column Names

Following is the code sample:

# Create an empty data frame with column names
edf <- data.frame( "First Name" = character(0), "Age" = integer(0))
# Data frame summary information using str

Following gets printed:

'data.frame':	0 obs. of  2 variables:
 $ First.Name: Factor w/ 0 levels: 
 $ Age       : int 


Create non-empty Dataframe with Column Names

Following is the code sample:

# Assign names to x 
x <- c( "Calvin", "Chris", "Raj")
# Assign names to y
y <- c( 10, 25, 19)
# Create a non-empty data frame with column names 
# Assign x to "First Name" as column name 
# Assign y to "Age" as column name 
nedf <- data.frame( "First Name" = x, "Age" = y)
# Print the data frame

Following gets printed. Note the column names such as “First Name” and “Age”

  First.Name Age
1     Calvin  10
2      Chris  25
3        Raj  19
