R "Hello World" Program

A simple program to display "Hello World!" on the screen using print() function.

To understand this example, you should have the knowledge of the following R programming topics:

Example: Hello World Program

> # We can use the print() function
> print("Hello World!")
[1] "Hello World!"
> # Quotes can be suppressed in the output
> print("Hello World!", quote = FALSE)
[1] Hello World!
> # If there are more than 1 item, we can concatenate using paste()
> print(paste("How","are","you?"))
[1] "How are you?"

In this program, we have used the built-in function print() to print the string Hello World!

The quotes are printed by default. To avoid this we can pass the argument quote = FALSE.

If there are more than one item, we can use the paste() or cat() function to concatenate the strings together.
