I am attempting to create a vignette in R Markdown for a package that I have created. Within one of these R functions, it has a readline() requiring user input to confirm continuing an analysis based on certain thresholds. This works in the terminal, as the user can simply answer the question. However, for an R Markdown it automatically spits out a warning. Is there a way to get around this functionality, or to prespecify the user response, or is this not a possibility within R markdown?
