What is an actual syntax of input funtion in R? is that readLine or readLines?

Answer 1

Okay, I think I can replicate the problem. When you want to get user input on your local R installation, use readline().

readLines reads a connection – that is how sololearn playground gets input. If you try it on your own computer, R gets trapped by itself which freezes or crashes R console

Answer 2

Input is covered in the sololearn R course. Check the lesson again or just try it on playground.

Also, you can get the documentation with ?readLines

Answer 3

What does the error message say?
Can you put your code in a script on playground?

Answer 4

Yes, And that syntax is not running in Rstudio.It is showing Error..

Answer 5

Yeah... That's what happened I think
