plotFront

The function expects a data.frame or a matrix. By default the first
2 or 3 columns/rows are assumed to contain the elements of the approximation sets.
Depending on the number of numeric columns (in case of a data.frame) or the
number of rows (in case of a matrix) the function internally calls
<code>plotScatter2d</code> or <code>plotScatter3d</code>.

Framework for building evolutionary algorithms for both single- and multi-objective continuous or discrete optimization problems. A set of predefined evolutionary building blocks and operators is included. Moreover, the user can easily set up custom objective functions, operators, building blocks and representations sticking to few conventions. The package allows both a black-box approach for standard tasks (plug-and-play style) and a much more flexible white-box approach where the evolutionary cycle is written by hand.

plotFront function

<dl><dt>x</dt>
<dd>[<code>matrix</code> | <code>data.frame</code>] 
Object which contains the approximations sets.</dd>
<dt>obj.names</dt>
<dd>[<code>character</code>] 
Optional objectives names.
Default is <code>c("f1", "f2")</code>.</dd>
<dt>minimize</dt>
<dd>[<code>logical</code>] 
Logical vector with ith entry <code>TRUE</code> if the ith objective shall be minimized.
If a single logical is passed, it is assumed to be valid for each objective.
If the matrix is of type <code>ecr_fitness_matrix</code> (this is the case if it is
produced by one of ecr2's utility functions, e.g. <code>evaluateFitness</code>),
the appended <code>minimize</code> attribute is the default.</dd>
