R Introduction
R is a programming language made for working with data. Even a two line script can do real work with data.
Print a line of text
This line prints one piece of text. The text appears in the output with quotes.
print("Data tells a story")Print a calculation
This line prints the result of a multiplication. The answer 100 appears in the output.
print(25 * 4)Print text and a number
The first line prints a label. The second line prints a multiplication result.
print("Team score")
print(7 * 6)Example
print("Daily sales report")
print(150 + 50)Key points
- R is used for statistics and careful work with data.
- R works with tables of data and builds summaries.
- An R script is a plain text file.
- This course uses base R with no add-ons.
- print() sends a value to the output.
In this example the first line prints a title for the report. The second line adds two numbers and prints the total.
