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 understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
