Dear authors of the package, 

first of all my appreciation for the great package! I'm fairly new with diving into the details of the package, so far I have been mostly using the flowpeaks function in a basic form from some scripts provided by a colleague. 

When I have the time I hope to dive deeper into the features of the package I have not yet discovered. 

My apologies for double posting a possibly simple question, but how can I grab the error rate value so that I can send that value to a print field in my Shiny app that i'm building? 

Thank you, 

Mark
