I want to pause my R script until the user presses a key.
我该怎么做?
推荐答案
正如已经在评论中写过某人一样，您不必在readline()之前使用猫.只需写:
As someone already wrote in a comment, you don't have to use the cat before readline(). Simply write:
readline(prompt="Press [enter] to continue")
如果您不想将其分配给变量并且不想在控制台中打印退货，请将readline()包裹在invisible()中:
If you don't want to assign it to a variable and don't want a return printed in the console, wrap the readline() in an invisible():
invisible(readline(prompt="Press [enter] to continue"))
