How to pause a for loop in R?

In R programming language, pausing a for loop can be achieved by using the Sys.sleep() function. This function is used to pause execution for a specific duration. You can place the Sys.sleep() function between each iteration of the for loop to achieve the pausing effect.

Below is an example:

for (i in 1:10) {
  # 执行某些操作
  print(i)
  
  # 暂停1秒钟
  Sys.sleep(1)
}

In the example above, the current iteration number i is printed and a 1-second pause is added before moving on to the next iteration. You can adjust the parameter in the Sys.sleep() function to control the length of the pause as needed.
