R: Graphical parameter for missing data plots

mdc {mice} | R Documentation

## 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.
