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.

## Arguments

- num_df
Degrees of freedom associated with the numerator of f statistic.

- den_df
Degrees of freedom associated with the denominator of f statistic.

- normal
If

`TRUE`

, normal curve with same`mean`

and`sd`

as the F distribution is drawn.- print_plot
logical; if

`TRUE`

, prints the plot else returns a plot object.- probs
Probability value.

- type
Lower tail or upper tail.

- perc
Quantile value.

## Examples

```
# visualize F distribution
vdist_f_plot()
vdist_f_plot(6, 10, normal = TRUE)
# visualize probability from a given quantile
vdist_f_perc(0.95, 3, 30, 'lower')
vdist_f_perc(0.125, 9, 35, 'upper')
# visualize quantiles out of given probability
vdist_f_prob(2.35, 5, 32)
vdist_f_prob(1.5222, 9, 35, type = "upper")
