Fills the background color of a column using a gradient based on the values given by an expression

rule_fill_gradient2(
  x,
  columns,
  expression,
  low = scales::muted("red"),
  mid = "white",
  high = scales::muted("blue"),
  midpoint = NA,
  space = "Lab",
  na.value = "#7F7F7F",
  limits = NA,
  lockcells = FALSE
)

Arguments

x

A condformat object, typically created with condformat()

columns

A character vector with column names to be colored. Optionally tidyselect::language() can be used.

expression

an expression to be evaluated with the data. It should evaluate to a logical or an integer vector, that will be used to determine which cells are to be colored.

low

colour for low end of gradient.

mid

colour for mid point

high

colour for high end of gradient.

midpoint

the value used for the middle color (the median by default)

space

colour space in which to calculate gradient. Must be "Lab" - other values are deprecated.

na.value

fill color for missing values

limits

range of limits that the gradient should cover

lockcells

logical value determining if no further rules should be applied to the affected cells.

Value

The condformat_tbl object, with the added formatting information
