Export Nicely-Formatted Data Frame in R (2 Examples)
In this R tutorial you’ll learn how to return a nicely-formatted data frame as PDF or txt file.
The article consists of this content:
Let’s do this!
Creation of Example Data
As a first step, let’s create some example data in R:
data <- data.frame(x1 = 1:5, # Example data x2 = LETTERS[1:5], x3 = 3, x4 = c("Hello", "What's up", "AAA", "x", "Y")) data # Return data to console # x1 x2 x3 x4 # 1 1 A 3 Hello # 2 2 B 3 What's up # 3 3 C 3 AAA # 4 4 D 3 x # 5 5 E 3 Y
The previous output of the RStudio console shows the structure of our example data: It’s a data frame containing five rows and four columns.
Example 1: Print Data Frame as PDF-File Using gridExtra Package
install.packages("gridExtra") # Install & load gridExtra library("gridExtra")
Now, we can save our example data in a publication ready design by using the grid.table function as shown below:
pdf("data_gridExtra.pdf") # Export PDF grid.table(data) dev.off()
Figure 1 shows the output of the previous R syntax – A pretty data matrix printed to a PDF file.
Example 2: Print Data Frame as txt-File Using stargazer Package
install.packages("stargazer") # Install & load gridExtra library("stargazer")
Now, we can use the stargazer function to return our example data as txt:
stargazer(data, # Export txt summary = FALSE, type = "text", out = "data_stargazer_txt.txt")
Figure 2 illustrates how our txt file looks like.
Note that you can use the stargazer function to export many different file-types such as LaTeX code or HTML/CSS code. You simply need to change the type argument within the stargazer command accordingly.
