I'm running code in R studio. When my script finishes running, I get the orange message `There were 50 or more warnings (use warnings() to see the first 50)` at the bottom of my result (and in practice, I suspect the number of warnings is in the tens of thousands, at a minimum). Are these warnings slowing down my code because they're I/O operations and therefore expensive? I'm not seeing any error messages, but I'm not sure if the way R studio handles them, if they're still I/O operations, or if whatever way it's handling them deals with the slowdown I would normally expect such a large number of I/O operations to cause.
