These functions are used by diamondPlot to construct a diamond plot. It's normally not necessary to call this function directly: instead, use meansDiamondPlot, meanSDtoDiamondPlot, and factorLoadingDiamondCIplot.

jitterWidth = 0.5, jitterHeight = 0.4,
size = 3, ...)A dataframe (or matrix) containing lower bounds, centers (e.g. means), and upper bounds of intervals (e.g. confidence intervals) for ggDiamondLayer or items and raw data for varsToDiamondPlotDf and rawDataDiamondLayer.
The columns in the dataframe with the lower bounds, centers (e.g. means), and upper bounds (in that order).
The column in the dataframe containing the colors for each diamond, or a vector with colors (with as many elements as the dataframe has rows).
When specifying a gradient using generateColors, it is usually desirable to specify the minimum and maximum possible value corresponding to the outer anchors of that gradient. For example, when plotting numbers from 0 to 100 using a gradient from 'red' through 'orange' to 'green', none of the means may actually be 0 or 100; the lowest mean may be, for example, 50. If no fullColorRange is specified, the diamond representing that lowest mean of 50 wil be red, not orange. When specifying the fullColorRange, the lowest and highest 'colors' in generateColors are anchored to the minimum and maximum values of fullColorRange.
When no colors are automatically generated, all diamonds will have this color.
If NA, lines will have the same colors as the diamonds' fill. If not NA, must be a valid color, which is then used as line color. Note that e.g. linetype and color can be used as well, which will be passed on to geom_polygon.
A vector of values, or the index of the column in the dataframe, that specifies the values for the Y axis of the diamonds. This should normally just be a vector of consecutive integers.
Whether to make the height of each diamond conditional upon its length (the width of the confidence interval).
If not using relative heights, fixedSize determines
the height to use.
Any additional arguments are passed to geom_polygon. This can be used to set, for example, the alpha value of the diamonds. Additional arguments for rawDataDiamondLayer are passed on to geom_jitter.
A vector of 2 or more values that are used to construct the diamond coordinates. If three values are provided, the middle one becomes the diamond's center. If two, four, or more values are provided, the median becomes the diamond's center.
The value on the other axis to use to compute the coordinates; this will be the Y axis value of the points of the diamond (if direction is 'horizontal') or the X axis value (if direction is 'vertical').
Whether the diamonds should be constructed horizontally or vertically.
The items from the dataframe to include in the diamondplot or dataframe.
The item labels to add to the dataframe.
Whether to sort the items (rows) in the dataframe decreasing (TRUE), increasing (FALSE), or not at all (NULL).
The confidence of the confidence intervals.
Order of the items to use (if not sorting).
This determines the alpha (transparency) of the data points.
The color of the data points.
How much to jitter the individual datapoints horizontally.
How much to jitter the individual datapoints vertically.
The size of the data points.
ggDiamondLayer returns a ggplot geom_polygon object, which can then be used in ggplot plots (as diamondPlot does).
diamondCoordinates returns a set of four coordinates that together specify a diamond.
varsToDiamondPlotDf returns a dataframe of diamondCoordinates.
rawDataDiamondLayer returns a geom_jitter object.
