## Plot helpers

### Description

Functions that are useful for customising plots and for creating your own plot functions.

### Usage

    Log10BLabel(community, name = "italic(B)", units = with(CPS(community),
                paste(M.units, "~", N.units)))
    Log10MLabel(community, name = "italic(M)", units = CPS(community)$M.units)
    Log10NLabel(community, name = "italic(N)", units = CPS(community)$N.units)

    DefaultCategoryColours()
    DefaultCategoryLabelColours()
    DefaultCategorySymbols()
    DefaultLinkColour()

    PlaceMissingPoints(x, xlim, y, ylim)

    LMabline(model, ...)
    PlotLinearModels(models, colour.spec, col, ...)
    FormatLM(model, slope.95.ci = FALSE, ci.plus.minus.style = FALSE,
             r = FALSE, r.squared = TRUE, model.var.names = TRUE, dp = 2)

### Arguments

`community` | an object of class `Community`.
`name` | the name that appears in the label.
`units` | the units that appears in the label.
`x` | x values.
`y` | y values.
`xlim` | limits of the x axis.
`ylim` | limits of the y axis.
`models` | a `list` of `lm` objects to be plotted.
`colour.spec` | either `NULL` or a named vector that maps values of `colour.by` to plotting values; defaults to the vector returned by `DefaultCategoryColours`.
`col` | plot colours.
`model` | an `lm` object for which a textual description is assembled.
`slope.95.ci` | logical - if `TRUE` then the 95% confidence intervals are included in the description.
`ci.plus.minus.style` | logical - if `TRUE` then the 95% confidence intervals are shown by a ‘plus-minus’ sign. If `FALSE` then the confidence intervals are shown by an upper and lower bound.
`r` | logical - if `TRUE` then ‘r’ is included in the description.
`r.squared` | logical - if `TRUE` then ‘r squared’ is included in the description.
`model.var.names` | logical - if `TRUE` then the names of the dependent and independent variables fitted in the model are included in the description. If `FALSE`, the names ‘x’ and ‘y’ are used.
`dp` | the number of decimal places to which values are presented.
`...` | other values passed to plotting functions.
