## Seed predation data set from Duncan and Duncan 2000

### Description

Data on seed predation over time from Duncan and Duncan (2000)

### Usage

    data(SeedPred)
    data(SeedPred_wide)
    data(SeedPred_mass)

### Format

`station`

  a factor specifying the station number

`species`

  a factor with levels `abz` `cd` `cor` `dio` `mmu` `pol` `psd` `uva`

`date`

  sample date

`seeds`

  number of seeds present

`tcum`

  cumulative time elapsed

`tint`

  time since last sample

`taken`

  seeds removed since last sample

`dist`

  distance from forest edge (m)

### Details

`SeedPred` is in long format, `SeedPred_wide` is in wide format; `SeedPred_wide` has lots of `NA` values because stations at 10 and 25 m from the forest were sampled on different days. `SeedPred_mass` is a numeric vector containing the approximate seed masses for each species.
