rule_fill_gradient(x, columns, expression, low = "#132B43",
  high = "#56B1F7", 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 coloured. Optionally tidyselect::select_helpers() can be used.

expression

an expression to be evaluated with the data. It should evaluate to a numeric vector, that will be used to determine the colour gradient level.

low

colour for low end of gradient.

high

colour for high end of gradient.

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.

...

Dots are used to transition from the old syntax rule_fill_discrete_old to the new one

Details

The syntax in condformat rules has changed since v0.7. See rule_fill_gradient_old

Value

The condformat_tbl object, with the added formatting information
