### Format

`toxicity` is a list of 3 components.

tab

### Examples

    data(toxicity)
    if(adegraphicsLoaded()) {

        ptable.margin = list(b = 5, l = 25, t = 25, r = 5), ptable.y.pos = "left", pgrid.draw = TRUE)
      table.value(toxicity$tab, labelsy = toxicity$species, labelsx = toxicity$chemicals,
        ptable.margin = list(b = 5, l = 5, t = 25, r = 26))
    } else {
      table.paint(toxicity$tab, row.lab = toxicity$species, col.lab = toxicity$chemicals)
      table.value(toxicity$tab, row.lab = toxicity$species, col.lab = toxicity$chemicals)
    }
