getPaletteCDISC: Get standard palette for typical CDISC variables.

In clinUtils: General Utility Functions for Analysis of Clinical Data

Get standard palette for typical CDISC variables.

Description

The extraction of the palette elements is case-insensitive.

Usage

getPaletteCDISC(x, var, type, palette = NULL)

Arguments

x	Character vector of factor with variable to consider. The palette is built based on the unique elements of this vector, or levels if x is a factor.
var	String with type of variable, among: 'NRIND': Normal Reference Range Indicator
type	String with type of palette: 'shape': shape/symbol palette
palette	(optional) Named vector with extra palette, e.g. to specify elements for non-standard categories. This palette is combined with the standard palette.

Details

The order of the palette depends on the type of the input variable (x):

• if a factor is specified, the palette is ordered based on its levels

• if a character vector is specified, the elements from the internal standard palette are used first, the remaining elements are then sorted alphabetically.

Value

Named vector with palette.

Examples

## palette for reference range indicator variables

xRIND <- c("LOW", "HIGH", "NORMAL", "NORMAL", "NORMAL", "ABNORMAL")

# get standard palette
getPaletteCDISC(x = xRIND, var = "NRIND", type = "shape")
getPaletteCDISC(x = xRIND, var = "NRIND", type = "color")

# in case extra categories are specified:
xRIND <- c(xRIND, "High Panic")
# the symbols are set to numeric symbols
getPaletteCDISC(xRIND, var = "NRIND", type = "shape")
# use shapePalette to specify symbols for extra categories
getPaletteCDISC(xRIND, var = "NRIND", type = "shape", palette = c("High Panic" = "\u2666"))

# palette is case-insensitive
xRIND <- c("Low", "High", "Normal", "Normal", "Normal")
getPaletteCDISC(xRIND, var = "NRIND", type = "shape")
