theme_metan_minimal()

transparent_color()

ggplot_color(n)

alpha_color(color, alpha = 50)

Arguments

grid

Control the grid lines in plot. Defaults to "both" (x and y major grids). Allows also grid = "x" for grids in x axis only, grid = "y" for grid in y axis only, or grid = "none" for no grids.

col.grid

The color for the grid lines

color.background

The color for the panel background.

n

The number of colors. This works well for up to about eight colours, but after that it becomes hard to tell the different colours apart.

color

A color name.

alpha

An alpha value for transparency (0 < alpha < 1).
