rule_fill_gradient2: Fill column with sequential color gradient

In zeehio/condformat: Conditional Formatting in Data Frames

Fill column with sequential color gradient

Description

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

Usage

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

Examples

data(iris)
cf <- condformat(iris[c(1:5, 70:75, 120:125), ]) %>%
 rule_fill_gradient2(Sepal.Length) %>%
 rule_fill_gradient2(Species, expression=Sepal.Length - Sepal.Width)
## Not run: 
print(cf)

## End(Not run)

cf <- condformat(iris[c(1:5, 70:75, 120:125), ]) %>%
  rule_fill_gradient2("Petal.Length") %>%
  rule_fill_gradient2(starts_with("Sepal"), expression=Sepal.Length - Sepal.Width)
## Not run: 
print(cf)

## End(Not run)
