Description Usage Arguments Value Examples

Estiamtes regression coefficients for tip species curves from raw data. May be useful if wanting to perform methods without first performing ancestral curve reconstruction via the phylocurve() function.

1 2 | ```
get.tip.coefficients(formula, tree, data, ymin = 0.01, ymax = 0.99,
ylength = 30, species.identifier = "species", verbose = FALSE)
``` |

`formula` |
Formula for function-valued trait (currently only supports models of the form Y~X) |

`tree` |
A phylogenetic tree of class "phylo" |

`data` |
A data frame with data for tip curve estimation, where each row contains a single data point. A column named "species" has the species names corresponding to each data point, a predictor (X) variable and the response (Y) variable, which must be scaled between 0 and 1. |

`ymin` |
Because 0 and 1 are undefined for inverse logit functions, the minimum and maximum values are defaulted to .01 and .99. Can be adjusted as needed. |

`ymax` |
Because 0 and 1 are undefined for inverse logit functions, the minimum and maximum values are defaulted to .01 and .99. Can be adjusted as needed. |

`ylength` |
How many landmarks (points on the curve) to evaluate. |

`species.identifier` |
Default is "species". Can be changed if the column in data has a different species identifier name. |

`verbose` |
ether to print progress during tip curve coefficient estimation. |

Estimated regression coefficients of tip curves.
