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)

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.
