Visualize how changes in degrees of freedom affect the shape of the F distribution. Compute & visualize quantiles out of given probability and probability from a given quantile.

dist_f_plot(num_df = 4, den_df = 30, normal = FALSE)

dist_f_perc(probs = 0.95, num_df = 3, den_df = 30,
type = c("lower", "upper"))

dist_f_prob(perc, num_df, den_df, type = c("lower", "upper"))

## Arguments

num_df Degrees of freedom associated with the numerator of f statistic. Degrees of freedom associated with the denominator of f statistic. If TRUE, normal curve with same mean and sd as the F distribution is drawn. Probability value. Lower tail or upper tail. Quantile value.

## Value

Percentile for the probs based on num_df, den_df and type or probability value for perc based on num_df, den_df and type.
