Hello World Program in R Programming Language
> # 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.
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
