mizer (version 3.2.0)

setColours: Set line colours and line types to be used in mizer plots

Description

Used for setting the colour and type of lines representing "Total", "Resource", "Fishing", "Background", "External" and possibly other categories in plots.

Usage

setColours(params, colours)
getColours(params)
setLinetypes(params, linetypes)
getLinetypes(params)

Value

setColours: The MizerParams object with updated line colours

getColours(): A named vector of colours

setLinetypes(): The MizerParams object with updated linetypes

getLinetypes(): A named vector of linetypes

Arguments

params

A MizerParams object

colours

A named list or named vector of line colours.

linetypes

A named list or named vector of linetypes.

Details

Colours for names that already had a colour set for them will be overwritten by the colour you specify. Colours for names that did not yet have a colour will be appended to the list of colours.

If a name coincides with the name of a species, the linecolour (for setColours()) or linetype (for setLinetypes()) entry for that species in species_params and given_species_params is updated as well, so that the choice persists with the species. Alternatively you can set the linecolour and linetype variables in the species parameter data frame directly, see the example below.

You can use the same colours in your own ggplot2 plots by adding scale_colour_manual(values = getColours(params)) to your plot. Similarly you can use the linetypes with scale_linetype_manual(values = getLinetypes(params)).

Examples

params <- setColours(NS_params, list("Resource" = "red","Total" = "#0000ff"))
params <- setLinetypes(NS_params, list("Total" = "dotted"))
# Set colours and linetypes for species, either via setColours()/
# setLinetypes() or directly via the species parameter data frame
params <- setColours(params, list("Cod" = "black"))
species_params(params)["Cod", "linetype"] <- "dashed"
plotSpectra(params, total = TRUE)
getColours(params)
getLinetypes(params)
