plot-methods function

Methods for Function 'plot' in Package 'rmoo'

Method used to visualize the fitness of the individuals during the execution of the algorithms. methods

plot(x, y, ...)

## S4 method for signature 'nsga,missing'
plot(x, y = "missing", type = c("scatter", "pcp", "heatmap", "polar"), ...)

## S4 method for signature 'nsga1,missing'
plot(x, y = "missing", type = c("scatter", "pcp", "heatmap", "polar"), ...)

## S4 method for signature 'nsga2,missing'
plot(x, y = "missing", type = c("scatter", "pcp", "heatmap", "polar"), ...)

## S4 method for signature 'nsga3,missing'
plot(x, y = "missing", type = c("scatter", "pcp", "heatmap", "polar"), ...)

Arguments

• x, y: Objects of either class nsga1 , nsga2 , or nsga3 .

• ...: other arguments passed on to methods

  • "optimal": An argument passed to the "scatter" plot. A matrix of dimension equal to the fitness with which they are compared. This value can only be compared in 2 and 3 dimensional "scatter" plots.
  • "individual": An argument passed to the "heatmap" and "polar" plots. A vector that represents the fitness of the individuals to be displayed.

• type: Type of graph to draw, the graphs can be of the type "scatter", "pcp", "heatmap", or "polar"

Returns

A graph of the evaluated type.

Details

The following plots are available:

• "Scatter Plot"
• "Parallel Coordinate Plot"
• "Heat Map"
• "Polar Coordinate"

Examples

# Where 'out' is an object of class nsga1, nsga2, or nsga3.
# The plot method will by default plot a scatter plot.
#
# plot(out)
#
# The Parallel Coordinate Plot will be plotted if "pcp" is passed as a parameter to "type".
#
# plot(out, type="pcp")
#
# A heat map plot will be plotted if "heatmap" is passed as a parameter to "type"
# and a vector with the individuals to plot to "individual"
#
# plot(out, type = "heatmap", individual = c(1:5))
#
# A polar coordinate plot will be plotted if "polar" is passed as a parameter to "type"
# and a vector with the individuals to plot to "individual"
#
# plot(out, type = "polar", individual = c(1:5))
