Convert Named Vector to Data Frame in R (Example)


In this R programming tutorial you’ll learn how to convert a vector with names to the data.frame class.

The page looks as follows:

Let’s do this.


Creation of Example Data

First, let’s construct some example data:

vec <- 1:5                          # Create example vector
names(vec) <- letters[1:5]
vec                                 # Print vector
# a b c d e 
# 1 2 3 4 5

As you can see based on the previous output of the RStudio console, our example data is a named vector with five elements.


Example: Converting Named Vector to Data Frame Using data.frame & as.list Functions

This Example illustrates how to use the data.frame and as.list functions to convert a named vector to the data.frame data type. Have a look at the following R code:

data <- data.frame(as.list(vec))    # Convert to data.frame
data                                # Print data
#   a b c d e
# 1 1 2 3 4 5

As you can see in the previous output, our named vector was changed to become a data.frame.

  • Hi, which packages do you use? I tried but RStudio pulls out the following error:

    Error in as.dataframe(as.list(vectorname)) :
    could not find function “as.dataframe”

    I use the newest version of R and RStudio
