head(viagra)

# Use apa.d.table function
apa.d.table(iv = dose, dv = libido, data = viagra, filename = "ex1_d_table.doc")

## End(Not run)

Example output

      dose libido
1  Placebo      3
2  Placebo      2
3  Placebo      1
4  Placebo      1

  1. Placebo   2.20 1.30                            
                                                    
  2. Low Dose  3.20 1.30 0.77                       
                         [-0.55, 2.04]              
                                                    
  3. High Dose 5.00 1.58 1.93          1.24         
                         [0.34, 3.44]  [-0.17, 2.59]
                                                    

Note. M indicates mean. SD indicates standard deviation. d-values are estimates calculated using formulas 4.18 and 4.19
from Borenstein, Hedges, Higgins, & Rothstein (2009). d-values not calculated if unequal variances prevented pooling.
Values in square brackets indicate the 95% confidence interval for each d-value. 
The confidence interval is a plausible range of population d-values 
that could have caused the sample d-value (Cumming, 2014).
