Description Usage Arguments Value

Creates a random R expression by randomly growing its tree. In each step of growth,
with probability `subtreeprob`

, an operator is chosen from the function set `funcset`

.
The operands are then generated by recursive calls. If no function of matching range type exists,
a terminal (constant or input variable) will be generated instead. If no subtree is generated, a
constant will be generated with probability `constprob`

. If no constant is generated, an input
variable will be chosen randomly. The depth of the resulting expression trees can be bounded by the
`maxdepth`

parameter.
In contrast to `randexprGrow`

, this function respects sTypes of functions, input variables,
and constant factories. Only well-typed expressions are created.
`randexprTypedFull`

creates a random full expression tree of depth `maxdepth`

,
respecting type constraints.

`type` |
The (range) type the created expression should have. |

`funcset` |
The function set. |

`inset` |
The set of input variables. |

`conset` |
The set of constant factories. |

`maxdepth` |
The maximum expression tree depth. |

`constprob` |
The probability of generating a constant in a step of growth, if no subtree
is generated. If neither a subtree nor a constant is generated, a randomly chosen input variable
will be generated. Defaults to |

`subtreeprob` |
The probability of generating a subtree in a step of growth. |

`curdepth` |
(internal) The depth of the random expression currently generated, used internally in recursive calls. |

A new R expression generated by random growth.
