Plots the values of the infill criterion for a 1- and 2-dimensional numerical search space for a given OptState.

# S3 method for OptState
plot(x, scale.panels = FALSE, points.per.dim = 100, ...)

## Arguments

x [OptState] The OptState. [logical(1)] If TRUE the values in each panel will be scaled to [0,1]. [integer] Number of (regular spaced) points at which to evaluate the surrogate per dimension. Default is 100. [any] Not used.
