)A ggplot object.
A data frame or tibble.
Unquoted col and fill aesthetic variable.
Unquoted facet aesthetic variable.
Unquoted second facet variable.
Unquoted group aesthetic variable.
Unquoted text aesthetic variable.
Map additional aesthetics using the ggplot2::aes function (e.g. shape). Excludes colour, fill or alpha.
A ggplot2 character string stat.
Position adjustment. Either a character string (e.g."identity"), or a function (e.g. ggplot2::position_identity()).
A coordinate function from ggplot2 (e.g. ggplot2::coord_sf(clip = "off")).
Colours to use. A character vector of hex codes (or names).
Colour to use for NA values. A character vector of a hex code (or name).
Opacity. A number between 0 and 1.
Other arguments passed to the ggplot2::geom_sf function.
Title string.
Subtitle string.
TRUE or FALSE for vertical x gridlines. NULL guesses based on the classes of the x and y.
Axis title string. Use "" for no title.
TRUE or FALSE of horizontal y gridlines. NULL guesses based on the classes of the x and y.
Axis title string. Use "" for no title.
A scales::breaks_* function (e.g. scales::breaks_pretty()), or a vector of breaks.
For a continuous col variable, the type of colouring. Either "gradient" or "steps". Defaults to "gradient".
For a continuous col variable, any values that the limits should encompass (e.g. 0).
A function that takes the breaks as inputs (e.g. scales::label_comma()), or a vector of labels.
The place for the legend. Either "bottom", "right", "top" or "left". Or just the first letter of each.
The number of columns for the legend elements.
The number of rows for the legend elements.
Reverse the elements of the legend. Defaults to FALSE.
A vector to determine the limits of the colour scale.
For a continuous col variable, a scales::oob_* function of how to handle values outside of limits (e.g. scales::oob_keep). Defaults to scales::oob_keep.
For a continuous col variable, a scales::rescale function.
Legend title string. Use "" for no title.
For a numeric col variable, a transformation object (e.g. "log10", "sqrt" or "reverse").
A function that takes the breaks as inputs (e.g. scales::label_comma()), or a named vector of labels (e.g. c("value" = "label", ...)).
The number of columns of facets. Only applies to a facet layout of "wrap".
The number of rows of facets. Only applies to a facet layout of "wrap".
Whether facet scales should be "fixed" across facets, "free" in both directions, or free in just one direction (i.e. "free_x" or "free_y"). Defaults to "fixed".
Whether facet space should be "fixed" across facets, "free" to be proportional in both directions, or free to be proportional in just one direction (i.e. "free_x" or "free_y"). Defaults to "fixed". Only applies where the facet layout is "grid" and facet scales are not "fixed".
Whether the layout is to be "wrap" or "grid". If NULL and a single facet (or facet2) argument is provided, then defaults to "wrap". If NULL and both facet and facet2 arguments are provided, defaults to "grid".
Whether the facet layout is "grid", whether to switch the facet labels to the opposite side of the plot. Either "x", "y" or "both".
Legend title string. Use "" for no title.
Legend title string. Use "" for no title.
Legend title string. Use "" for no title.
Caption title string.
A function to format unspecified titles. Defaults to snakecase::to_sentence_case.
A ggplot2 theme.
