The progress bar can be set in two ways in SpaDES. First, by setting values in the .progress list element in the params list element passed to simInit. Second, at the spades call itself, which can be simpler. See examples.


# S4 method for simList

progressInterval(sim) <- value

# S4 method for simList
progressInterval(sim) <- value


# S4 method for simList

progressType(sim) <- value

# S4 method for simList
progressType(sim) <- value



A simList object from which to extract element(s) or in which to replace element(s).


The parameter value to be set (in the corresponding module and param).


Progress Bar: Progress type can be one of "text", "graphical", or "shiny". Progress interval can be a numeric. These both can get set by passing a .progress = list(type = "graphical", interval = 1) into the simInit call. See examples.
