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

dist_t_plot(df = 3)

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

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

Arguments

df Degrees of freedom. Probability value. Lower tail, upper tail, interval or both. Quantile value.

Value

Percentile for the probs based on df and type or probability value for the perc based on df and type.
