d.r: d to r

In phoebehlam/michaela: convert statistical metrics for meta-analytic purpose

d to r

Description

cohen's d to correlation coefficient

Usage

d.r(d, n1, n2, dir)

Arguments

d	cohen's d
n1	cell size of group 1 (if missing, defaults correction factor a = 4, assumes n1=n2)
n2	cell size of group 2 (if missing, defaults correction factor a = 4, assumes n1=n2)
dir	if cohen's d is in absolute value, provide the empirical direction: +1 for positive associaitons (e.g., group 1 - group 2 >= 0) and -1 for negative associations (e.g., group 1 - group 2 < 0)
k	total number of predictors

Examples

d.t(.80, 15, 20, 1, -1)
dat %>% mutate (t_from_d = d.t(cohend, stress_n, control_n, numpred, emp_dir)) -> dat
