Plot a boxplot with the data points superimposed. Box plots are aligned horizontally.
ScatterBoxPlotH( frm, xvar, yvar, title, ..., pt_alpha = 0.3, pt_color = "black", box_color = "black", box_fill = "lightgray" )
data frame to get values from
name of the continuous column in frame
name of the independent column in frame; assumed discrete
(doesn't take additional arguments, used to force later arguments by name)
transparency of points in scatter plot
boxplot line color
boxplot fill color (can be NA for no fill)
