dist_f: Plot F distributions

Description

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.

Usage

dist_f(f = NULL, deg.f1 = NULL, deg.f2 = NULL, p = NULL, xmax = NULL,
  geom.colors = NULL, geom.alpha = 0.7)

Examples

# a simple F distribution for 6 and 45 degrees of freedom
dist_f(deg.f1 = 6, deg.f2 = 45)

# F distribution for 6 and 45 degrees of freedom,
# and a shaded area starting at F value of two.
# F-values equal or greater than 2.31 are "significant"
dist_f(f = 2, deg.f1 = 6, deg.f2 = 45)

# F distribution for 6 and 45 degrees of freedom,
# and a shaded area starting at a p-level of 0.2
# (F-Value about 1.5).
dist_f(p = 0.2, deg.f1 = 6, deg.f2 = 45)
