Produces bar charts for multivariate analyses. Plots the contribution to the variance from each data point for upwards of two axes (components).

contributionBars(factor_scores, contributions, x_axis = 1, y_axis = 2, col = NULL, 
	main = NULL, upper = 'steelblue4', lower = 'firebrick2', threshold = 0, 
	sortContributions = TRUE, pretty = FALSE, show.bg.bars = FALSE)

`factor_scores`	The factor scores, or x- and y-axis points of a data set.
`contributions`	The amount of contribution to the variance (between 0-1) by each data point.
`x_axis`	Which axis is the x-axis? Default is 1.
`y_axis`	Which axis is the y-axis? Default is 2.
`col`	A single-column matrix of colors for each data point.
`main`	A title to be placed at the top of the graph.
`upper`	The color used to identify the upper bound items that contribute above average variance.
`lower`	The color used to identify the lower bound items that contribute above average variance.
`threshold`	A threshold (between 0-1) to draw upper and lower bounds for important items. Default is 1/number of items.
`sortContributions`	boolean, if TRUE, items will be sorted by contribution. if FALSE, items will appear in their row order.
`pretty`	a boolean. If FALSE, use the current version. If TRUE, make the bars with `prettyBars`.
`show.bg.bars`	a boolean. Only used if `pretty` is TRUE. If TRUE, background bars are plotted for a fill effect.
