tithonia {ade4} | R Documentation

## Phylogeny and quantitative traits of flowers

### Description

This data set describes the phylogeny of 11 flowers as reported by Morales (2000). It also gives morphologic and demographic traits corresponding to these 11 species.

### Usage

    data(tithonia)

### Format

`tithonia` is a list containing the 2 following objects :

tre

  is a character string giving the phylogenetic tree in Newick format.

tab

  is a data frame with 11 species and 14 traits (6 morphologic traits and 8 demographic).

### Details

Variables of `tithonia$tab` are the following ones :
morho1: is a numeric vector that describes the seed size (mm)
morho2: is a numeric vector that describes the flower size (mm)
morho3: is a numeric vector that describes the female leaf size (cm)
morho4: is a numeric vector that describes the head size (mm)
morho5: is a integer vector that describes the number of flowers per head
morho6: is a integer vector that describes the number of seeds per head
demo7: is a numeric vector that describes the seedling height (cm)
demo8: is a numeric vector that describes the growth rate (cm/day)
demo9: is a numeric vector that describes the germination time
demo10: is a numeric vector that describes the establishment (per cent)
demo11: is a numeric vector that describes the viability (per cent)
demo12: is a numeric vector that describes the germination (per cent)
demo13: is a integer vector that describes the resource allocation
demo14: is a numeric vector that describes the adult height (m)

### Source

Data were obtained from Morales, E. (2000) Estimating phylogenetic inertia in Tithonia (Asteraceae) : a comparative approach. Evolution, 54, 2, 475–484.

### Examples

    data(tithonia)
    phy <- newick2phylog(tithonia$tre)
    tab <- log(tithonia$tab + 1)
    table.phylog(scalewt(tab), phy)
    gearymoran(phy$Wmat, tab)
    gearymoran(phy$Amat, tab)
