mdc: Graphical parameter for missing data plots

In mice: Multivariate Imputation by Chained Equations

Graphical parameter for missing data plots

Description

mdc returns colors used to distinguish observed, missing and combined data in plotting. mice.theme return a partial list of named objects that can be used as a theme in stripplot, bwplot, densityplot and xyplot.

Usage

mdc(
  r = "observed",
  s = "symbol",
  transparent = TRUE,
  cso = grDevices::hcl(240, 100, 40, 0.7),
  csi = grDevices::hcl(0, 100, 40, 0.7),
  csc = "gray50",
  clo = grDevices::hcl(240, 100, 40, 0.8),
  cli = grDevices::hcl(0, 100, 40, 0.8),
  clc = "gray50"
)

Arguments

r	A numerical or character vector. The numbers 1-6 request colors as follows: 1=cso, 2=csi, 3=csc, 4=clo, 5=cli and 6=clc. Alternatively, r may contain the strings ' observed', 'missing', or 'both', or abbreviations thereof.
s	A character vector containing the strings 'symbol' or ' line', or abbreviations thereof.
transparent	A logical indicating whether alpha-transparency is allowed. The default is TRUE.
cso	The symbol color for the observed data. The default is a transparent blue.
csi	The symbol color for the missing or imputed data. The default is a transparent red.
csc	The symbol color for the combined observed and imputed data. The default is a grey color.
clo	The line color for the observed data. The default is a slightly darker transparent blue.
cli	The line color for the missing or imputed data. The default is a slightly darker transparent red.
clc	The line color for the combined observed and imputed data. The default is a grey color.

Details

This function eases consistent use of colors in plots. The default follows the Abayomi convention, which uses blue for observed data, red for missing or imputed data, and black for combined data.

Value

mdc() returns a vector containing color definitions. The length of the output vector is calculate from the length of r and s. Elements of the input vectors are repeated if needed.
