This function plots a simple F distribution or an F distribution with shaded areas that indicate at which F value a significant p-level is reached.
dist_f(f = NULL, deg.f1 = NULL, deg.f2 = NULL, p = NULL, xmax = NULL, geom.colors = NULL, geom.alpha = 0.7)
f | Numeric, optional. If specified, an F distribution with |
---|---|
deg.f1 | Numeric. The first degrees of freedom for the F distribution. Needs to be specified. |
deg.f2 | Numeric. The second degrees of freedom for the F distribution. Needs to be specified. |
p | Numeric, optional. If specified, a F distribution with |
xmax | Numeric, optional. Specifies the maximum x-axis-value. If not specified, the x-axis ranges to a value where a p-level of 0.00001 is reached. |
geom.colors | user defined color for geoms. See 'Details' in |
geom.alpha | Specifies the alpha-level of the shaded area. Default is 0.7, range between 0 to 1. |
