Add conditional formatting to cells

conditionalFormatting(
  wb,
  sheet,
  cols,
  rows,
  rule = NULL,
  style = NULL,
  type = "expression",
  ...
)

Arguments

wb

A workbook object
sheet

A name or index of a worksheet
cols

Columns to apply conditional formatting to
rows

Rows to apply conditional formatting to
rule

The condition under which to apply the formatting. See examples.
style

A style to apply to those cells that satisfy the rule. Default is createStyle(fontColour = "#9C0006", bgFill = "#FFC7CE")
type

Either 'expression', 'colourScale', 'databar', 'duplicates', 'beginsWith', 'endsWith', 'topN', 'bottomN', 'contains' or 'notContains' (case insensitive).
...

See below

Details

See Examples.

If type == "expression"

  • style is a Style object. See createStyle

  • rule is an expression. Valid operators are "<", "<=", ">", ">=", "==", "!=".

If type == "colourScale"

  • style is a vector of colours with length 2 or 3

  • rule can be NULL or a vector of colours of equal length to styles

If type == "databar"

  • style is a vector of colours with length 2 or 3

  • rule is a numeric vector specifying the range of the databar colours. Must be equal length to style

  • ...

    • showvalue If FALSE the cell value is hidden. Default TRUE.

    • gradient If FALSE colour gradient is removed. Default TRUE.

    • border If FALSE the border around the database is hidden. Default TRUE.

If type == "duplicates"

  • style is a Style object. See createStyle

  • rule is ignored.

If type == "contains"

  • style is a Style object. See createStyle

  • rule is the text to look for within cells

If type == "between"

  • style is a Style object. See createStyle

  • rule is a numeric vector of length 2 specifying lower and upper bound (Inclusive)

If type == "topN"

  • style is a Style object. See createStyle

  • rule is ignored

  • ...

    • rank numeric vector of length 1 indicating number of highest values.

    • percent TRUE if you want top N percentage.

If type == "bottomN"

  • style is a Style object. See createStyle

  • rule is ignored

  • ...

    • rank numeric vector of length 1 indicating number of lowest values.

    • percent TRUE if you want bottom N percentage.
