   The key difference is the distinction they make in the Shiny documentation, between reactive "sources" and "conductors." In that terminology, reactive({...}) is a conductor, but reactiveValues can only be a source.

   The reactiveVal function is used to construct a "reactive value" object. This is an object used for reading and writing a value, like a variable, but with special capabilities for reactive programming.

   Reactive expressions are expressions that can read reactive values and call other reactive expressions. Whenever a reactive value changes, any reactive expressions that depended on it are marked as "invalidated" and will automatically re-execute if necessary.

   This function returns an object for storing reactive values. It is similar to a list, but with special capabilities for reactive programming. When you read a value from it, the calling reactive expression takes a reactive dependency on that value, and when you write to it, it notifies any reactive functions that depend on that value.

   Statistics, like all other branches of mathematics, uses mathematical models to describe phenomena that occur in the real world. Some mathematical models are deterministic. These models can be used when one value is precisely determined from another value.

   What's the difference between reactive values and reactivevalues?

   • In that terminology, reactive({...}) is a conductor, but reactiveValues can only be a source. Here's how I think of reactiveValues - as a way to extend input which gets specified in UI.R. Sometimes, the slots in input are not enough, and we want derived values based on those input slots.

   What is a reactiveval object?

   • This is an object used for reading and writing a value, like a variable, but with special capabilities for reactive programming. When you read the value out of a reactiveVal object, the calling reactive expression takes a dependency, and when you change the value, it notifies any reactives that previously depended on that value.

   What happens when you read a value out of a reactiveval object?

   • When you read the value out of a reactiveVal object, the calling reactive expression takes a dependency, and when you change the value, it notifies any reactives that previously depended on that value. An optional initial value. An optional label, for debugging purposes (see reactlog() ). If missing, a label will be automatically created.
