dist_t: Plot t-distributions

Description

This function plots a simple t-distribution or a t-distribution with shaded areas that indicate at which t-value a significant p-level is reached.

Usage

dist_t(t = NULL, deg.f = NULL, p = NULL, xmax = NULL,
  geom.colors = NULL, geom.alpha = 0.7)

Examples

# a simple t-distribution
# for 6 degrees of freedom
dist_t(deg.f = 6)

# a t-distribution for 6 degrees of freedom,
# and a shaded area starting at t-value of one.
# With a df of 6, a t-value of 1.94 would be "significant".
dist_t(t = 1, deg.f = 6)

# a t-distribution for 6 degrees of freedom,
# and a shaded area starting at p-level of 0.4
# (t-value of about 0.26).
dist_t(p = 0.4, deg.f = 6)
