Examples
Parameters
One or more faceting variable names.
Number of columns.
Number of rows.
Specifies whether scales are shared across all facets. default = "fixed" (shared) , "free" - vary across both rows and columns, "free_x" or "free_y" - vary across rows or columns respectively.
default = 1. Specifies ordering direction panels. 1 - ascending, -1 - descending, null - ascending. The order values are positionally matched to variables in facets.
Specifies the format pattern for displaying faceting values. The format values are positionally matched to variables in facets.
Specifies whether to drop unused factor levels (the default behavior) or to show all factor levels regardless of whether they occur in the data.
Direction: either "h" for horizontal, the default, or "v", for vertical.
Specifies the maximum label length (in characters) before a line break is applied. The labWidth values are positionally matched to variables in facets.
Format patterns in the format parameter can be just a number format (like "d") or a string template where number format is surrounded by curly braces: "{d} cylinders". Note: the "$" must be escaped as "\$". For more info see: formats.html
Examples:
".2f" -> "12.45";
