In my R program, I would like the user to raise a query ( pressing keys )at any point of the simulation. When a query is detected, then the simulation is paused and script written for that query should run.How can I do this?
check for interrupt{
run the interrupt script
}
continue main simulation.
Could you please elaborate more on your question? It is not clear enough what your problem is.
I would really encourage you to review the following guide, FAQ: Tips for writing R-related questions.
For example, the guide emphasizes asking coding questions with formatted code-chunks and a reprex.
You may have noticed folks here requesting minimal reprexes, that's because asking questions this way saves answerers a lot of time.
Reproducible Examples:
help make your question clear and replicable
increases the probability folks will reach out and try to help,
reduces the number of back-and-forths required to understand the question,
and makes your question and suggested solutions more useful to folks in the future researching similar problems.
