tithonia | R Documentation |

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.

data(tithonia)

`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).

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)

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