I'm working on a shiny app and I'm running into difficulty with observeEvent() function when creating a complex expression of multiple inputs that all derive from selectInput()..

Enzo - Use a vector for all the inputs/reactives you want to trigger the observeEvent (inputs trigger when their value changes ). Then do your observeEvent ( c (trigger1, trigger2, trigger3...), { code }). Do any ANDs and ORs in the code section. You probably want to AND and OR on the *value* of the trigger anyhow, not on whether it has changed.R shiny modules with reactive input not working.

Shiny's reactive programming framework is primarily designed for calculated values (reactive expressions) and side-effect-causing actions (observers) that respond to any of their inputs changing. That's often what is desired in Shiny apps, but not always: sometimes you want to wait for a specific action to be taken from the user, like clicking an actionButton, before calculating an ....
