An S4 class to return the results of using a GA to estimate a FSM with evolve_model.

An S4 class to return the results of using a GA to estimate a FSM with evolve_model.

Turns ga_fsm S4 object into list of summaries for printing and then prints it.

Plots ga_fsm S4 object's state transition matrix

Plots ga_fsm S4 object's variable importances

Extracts slot relevant to estimating the fsm

Extracts performance

Extracts slot of variable importances

Extracts slot of action_vec

Extracts number of states

Predicts new data with estimated model

Arguments

x	S4 ga_fsm object. @export
...	arguments to be passed to/from other methods.
object	S4 ga_fsm object
digits	Optional numeric vector length one for how many significant digits to print, default is 3. @export
y	not used.
maintitle	optional character vector
action_label	optional character vector same length as action vector, where each ith element corresponds to what that ith element in the action vector represents. This will be used to fill in the states (circles) of the state transition matrix to be plotted.
transition_label	optional character vector same length as number of columns of state transition matrix.
curvature	optional numeric vector specifying the curvature of the lines for a diagram of 2 or more states.
height	ga_fsm S4 object
labels	vector of labels for each point. For vectors the default is to use names(x) and for matrices the row labels dimnames(x)[[1]].
data	A `data.frame` that has columns named "period" and "outcome" (period is the time period that the outcome action was taken), and one to three additional columns, containing predictors. All of the 3-5 columns should be named. The period and outcome columns should be integer vectors and the columns with the predictor variable data should be logical vectors (`TRUE, FALSE`). If the predictor variable data is not logical, it will coerced to logical with `base::as.logical()`.
type	Not currently used.
na.action	Optional function.

Slots

call: Language from the call of the function evolve_model.
actions: Numeric vector with the number of actions.
states: Numeric vector with the number of states.
GA: S4 object created by ga() from the GA package.
state_mat: Numeric matrix with rows as states and columns as predictors.
action_vec: Numeric vector indicating what action to take for each state.
predictive: Numeric vector of length one with test data accuracy if test data was supplied; otherwise, a character vector with a message that the user should provide test data for better estimate of performance.
