Enables a conversion between Probability of Direction (pd) and pvalue.
Usage
pd_to_p(pd, direction = "twosided", verbose = TRUE, ...)
p_to_pd(p, direction = "twosided", ...)
convert_p_to_pd(p, direction = "twosided", ...)
convert_pd_to_p(pd, direction = "twosided", verbose = TRUE, ...)
Arguments
 pd
A Probability of Direction (pd) value (between 0 and 1).
 direction
What type of pvalue is requested or provided. Can be
"twosided"
(default, two tailed) or"onesided"
(one tailed). verbose
Toggle off warnings.
 ...
Arguments passed to or from other methods.
 p
A pvalue.
Details
Conversion is done using the following equation (see Makowski et al., 2019):
When direction = "twosided"

$$p = 2 \times (1  p_d)$$
When direction = "onesided"

$$p = 1  p_d$$
Note that this conversion is only valid when the lowest possible values of pd
is 0.5  i.e., when the posterior represents continuous parameter space (see
p_direction). If any pd < 0.5 are detected, they are converted to a p of 1,
and a warning is given.
