Arguments

Format

A data frame with 136 observations on the following 31 variables.

pdias: Diaspore mass (mg).

mycor: Mycorrhizae, an ordered factor with levels '0'never < '1' sometimes< '2'always.
vegaer: Aerial vegetative propagation, an ordered factor with levels '0'never < '1' present but limited< '2'important.
vegsout: Underground vegetative propagation, an ordered factor with 3 levels identical to 'vegaer' above.
autopoll: Selfing pollination, an ordered factor with levels '0'never < '1'rare < '2' often< the rule'3'.
insects: Insect pollination, an ordered factor with 5 levels '0' < ... < '4'.
wind: Wind pollination, an ordered factor with 5 levels '0' < ... < '4'.
lign: A binary factor with levels '0:1', indicating if plant is woody.
piq: A binary factor indicating if plant is thorny.
ros: A binary factor indicating if plant is rosette.
semiros: Semi-rosette plant, a binary factor ('0': no; '1': yes).
leafy: Leafy plant, a binary factor.
suman: Summer annual, a binary factor.
winan: Winter annual, a binary factor.
monocarp: Monocarpic perennial, a binary factor.

windgl: wind dispersed fruits, a binary factor.
unsp: Unspecialized mechanism of seed dispersal, a binary factor.

Details

Most of factor attributes are not disjunctive. For example, a plant can be usually pollinated by insects but sometimes self-pollination can occur.
