rasterTheme function

Themes for raster with lattice.

Auxiliary functions for the customization of trellis graphics with lattice.

xscale.raster and yscale.raster suppress the right and top axis, respectively. xscale.raster.subticks and yscale.raster.subticks also suppress those axis and draw subticks.

rasterTheme is a customization of the custom.theme.2 function of latticeExtra using the magma palette of the viridis

package. The other palettes provided by this package are available through the viridisTheme, infernoTheme, and plasmaTheme.

YlOrRdTheme, BuRdTheme, RdBuTheme, GrTheme

and BTCTheme are variations of rasterTheme using palettes of the RColorBrewer and hexbin packages.

streamTheme is a variation of rasterTheme using black for the region, gray for the panel background and a sequential palette for points.

bwTheme is a variation of rasterTheme for the bwplot methods.

Arguments

• lim: Range of data.
• pch: Symbol used for points.
• cex: A numeric multiplier to control the size of the points.
• region: A vector of colors that is used to define a continuous color gradient using colorRampPalette to fill in regions. Note that the length of this gradient is set by custom.theme to exactly 100 colors.
• symbol: A palette to display symbols.
• panel.background: Parameters of the panel background.
• alpha, ...: Additional arguments for custom.theme.2, yscale.components.default and xscale.components.default
• strip.background, strip.shingle, strip.border: List whose components define the configuration of the strip areas. Read the help page of trellis.par.get for details.
• add.lines: List whose components define the lines superposed on the graphic. Read the help page of trellis.par.get for details.
• box.rectangle: List whose components define the box of the boxplot.
• box.umbrella: List whose components define the whiskers of the boxplot.
• plot.polygon: List whose components define the violin plot.
• plot.symbol: List whose components define the raw points when draw.points = TRUE.
