Visualize how degrees of freedom affect the shape of t distribution, visualize quantiles out of given probability and probability from a given quantile.

vdist_t_plot(df = 3)

vdist_t_perc(probs = 0.95, df = 4, type = c("lower", "upper",
  "both"))

vdist_t_prob(perc, df, type = c("lower", "upper", "interval", "both"))

Arguments

df

Degrees of freedom.

probs

Probability value.

type

Lower tail, upper tail, interval or both.

perc

Quantile value.
