## Plant traits for 136 species

### Description

This dataset, from the library cluster, describes 136 plant species according to biological attributes (morphological or reproductive).

### Usage

`data(plantTraits)`

### Format

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

`pdias`

Diaspore mass (mg).

`longindex`

Seed bank longevity.

`durflow`

Flowering duration.

- height
Plant height, an ordered factor with levels '1' < '2' < ... < '8'.

`begflow`

Time of first flowering, an ordered factor with levels '1' < '2' < '3' < '4' < '5' < '6' < '7' < '8' < '9'.

`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.

`polycarp`

Polycarpic perennial, a binary factor.

`seasaes`

Seasonal aestival leaves, a binary factor.

`seashiv`

Seasonal hibernal leaves, a binary factor.

`seasver`

Seasonal vernal leaves, a binary factor.

`everalw`

Leaves always evergreen, a binary factor.

`everparti`

Leaves partially evergreen, a binary factor.

`elaio`

Fruits with an elaiosome (dispersed by ants), a binary factor.

`endozoo`

Endozoochorous fruits, a binary factor.

`epizoo`

Epizoochorous fruits, a binary factor.

`aquat`

Aquatic dispersal fruits, 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.
