CIBER

This function generates a high-level plot consisting of several diamond plots. This function is useful for estimating the relative relevance of a set of determinants of, for example, behavior. The plot in the left hand panel shows each determinant's distribution with a diamond representing the confidence interval. The right hand plot shows the determinants' associations to one or more 'target' variables, such as behavior or determinants of behavior.

Usage
CIBER(data, determinants, targets,
      conf.level = list(means = 0.9999,
                        associations = 0.95),
      subQuestions = NULL,
      leftAnchors = rep("Lo", length(determinants)),
      rightAnchors = rep("Hi", length(determinants)),
      orderBy = NULL, decreasing = NULL,
      generateColors = list(means = c("red", "blue", "green"),
                            associations = c("red", "grey", "green")),
      strokeColors = brewer.pal(9, "Set1"),
      titlePrefix = "Means and associations with",
      titleVarLabels = NULL, titleSuffix = "",
      fullColorRange = NULL, associationsAlpha = 0.5,
      returnPlotOnly = TRUE, drawPlot = TRUE,
      baseSize = 0.8, dotSize = 2.5 * baseSize,
      baseFontSize = 10 * baseSize,
      theme = theme_bw(base_size = baseFontSize), ...)

detStructCIBER(determinantStructure, dat, conf.level = list(means = 0.9999, associations = 0.95), subQuestions = NULL, leftAnchors = rep("Lo", length(determinants)), rightAnchors = rep("Hi", length(determinants)), orderBy = 1, decreasing = NULL, generateColors = list(means = c("red", "blue", "green"), associations = c("red", "grey", "green")), strokeColors = brewer.pal(9, "Set1"), titlePrefix = "Means and associations with", titleVarLabels = NULL, titleSuffix = "", fullColorRange = NULL, associationsAlpha = 0.5, baseSize = 0.8, dotSize = 2.5 * baseSize, baseFontSize = 10 * baseSize, theme = theme_bw(base_size = baseFontSize), ...)

Arguments
data, dat
The dataframe containing the variables.
determinants
The 'determinants': the predictors (or 'covariates') of the target variables(s) (or 'criteria').
targets
The 'targets' or 'criteria' variables: the variables predicted by the determinants.
determinantStructure
When using detStructCIBER, the determinant structure as generated by determinantStructure is included here. determinants, targets, subQuestions, leftAnchors, and rightAnchors are then read from the determinantStructure object. In other words: once a determinantStructure has been generated, only dat and determinantStructure have to be provided as argument to generate a CIBER diamond plot.
conf.level
The confidence levels for the confidence intervals: has to be a named list with two elements: means and associations, specifying the desired confidence levels for the means and associations, respectively. The confidence level for the associations is also used for the intervals for the proportions of explained variance.
subQuestions
The subquestions used to measure each determinants. This can also be used to provide pretty names for the variables if the determinants were not measured by one question each. Must have the same length as determinants.
leftAnchors
The anchors to display on the left side of the left hand panel. If the determinants were measured with one variable each, this can be used to show the anchors that were used for the respective scales. Must have the same length as determinants.
rightAnchors
The anchors to display on the left side of the left hand panel. If the determinants were measured with one variable each, this can be used to show the anchors that were used for the respective scales. Must have the same length as determinants.
orderBy
Whether to sort the determinants. Set to NULL to not sort at all; specify the name or index of one of the targets to sort by the point estimates of the associations with that target variable. Use decreasing to determine whether to sort in ascending or descending order. For convenience, if orderBy is not NULL, but decreasing is, the determinants are sorted in descending (decreasing) order.
decreasing
Whether to sort the determinants. Specify NULL to not sort at all, TRUE to sort in descending order, and FALSE to sort in ascending order. If decreasing is nor NULL, but orderBy is NULL, the determinants are sorted by their means. For convenience, if orderBy is not NULL, but decreasing is, the determinants are sorted in descending (decreasing) order.
generateColors
The colors to use to generate the gradients for coloring the diamonds representing the confidence intervals. Has to be a named list with two elements: means and associations, specifying the desired colors for the means and associations, respectively.
strokeColors
The palette to use to color the stroke of the confidence intervals for the associations between the determinants and the targets. Successive colors from this palette are used for the targets.
titlePrefix
Text to add before the list of target names and the proportions of explained variance for each target. This plot title also serves as legend to indicate which target 'gets' which each color.
titleVarLabels
Optionally, variable labels to use in the plot title. Has to be the exact same length as targets.
titleSuffix
Text to add after the list of target names and the proportions of explained variance for each target.
fullColorRange
If colors are specified, this can be used to specify which values, for the determinant confidence intervals in the left hand panel, are the minimum and maximum. This is useful if those scores are not actually in the data (e.g. for extremely skewed distributions). If NULL, the range of all individual scores on the determinants is used. For the associations, c(-1, 1) is always used as fullColorRange.
associationsAlpha
The alpha level (transparency) of the confidence interval diamonds in the right hand plot. Value between 0 and 1, where 0 signifies complete transparency (i.e. invisibility) and 1 signifies complete 'opaqueness'.
returnPlotOnly
Whether to return the entire object that is generated (including all intermediate objects) or only the plot.
drawPlot
Whether the draw the plot, or only return it.
baseSize
This can be used to efficiently change the size of most plot elements.
dotSize
This is the size of the points used to show the individual data points in the left hand plot.
baseFontSize
This can be used to set the font size separately from the baseSize.
theme
This is the theme that is used for the plots.
These arguments are passed on to biAxisDiamondPlot (for the left panel) and diamondPlot (for the right panel). Note that all argument are passed to both those functions.
Details

Details are explained in Crutzen & Peters (2017).

Value

Depending on the value of returnPlotOnly, either the plot only (a gtable object) or an object containing most objects created along the way (in which case the plot is stored in $output$bla).

The plot has width and height attributes which can be used when saving the plot.
