This function produces is a diamondplot that plots the confidence intervals for associations between a number of covariates and a criterion. It currently only supports the Pearson's r effect size metric; other effect sizes are converted to Pearson's r.

The dataframe containing the relevant variables.
The covariates: the list of variables to associate to the criterion or criteria, usually the predictors.
The criteria, usually the dependent variables; one
criterion (one dependent variable) can also be specified of course. The
The labels for the covariates, for example the questions that were used (as a character vector).
The labels for the criteria (in the legend).
Whether to sort the covariates by the point estimate of
the effect size of their association with the criterion. Use
When specifying multiple criteria, this can be used to indicate by which criterion the items should be sorted (if they should be sorted).
The confidence of the confidence intervals.
The colors to use for the different
associations can be specified in
Whether to return the entire object that is generated, or just the resulting ggplot2 layer.
The effect size metric to plot - currently, only 'r' is supported, and other values will return an error.
The transparency (alpha channel) value of the
diamonds for each association can be specified in
Whether to show the legend.
The label to use for the x and y axes (for
The thickness of the lines (the diamonds' strokes).
A file to which to save the plot.
Width and height of saved plot (specified in
centimeters by default, see
Parameters to pass to ggsave when saving the plot.
associationsToDiamondPlotDf is a helper function that produces the required dataframe.
This function can be used to quickly plot multiple confidence intervals.
