  iv,
  dv,
  data,
  filename = NA,
  table.number = 0,
  show.conf.interval = TRUE,
  landscape = TRUE
)

Arguments

iv: Name of independent variable column in data frame for all paired comparisons
dv: Name of dependent variable column in data frame for all paired comparisons
data: Project data frame name
filename: (optional) Output filename document filename (must end in .rtf or .doc only)
table.number: Integer to use in table number output line
show.conf.interval: (TRUE/FALSE) Display confidence intervals in table. This argument is deprecated and will be removed from later versions.
landscape: (TRUE/FALSE) Make RTF file landscape

Value

APA table object

Examples

# View top few rows of viagra data set from Discovering Statistics Using R
head(viagra)
#>       dose libido
#> 1  Placebo      3
#> 2  Placebo      2
#> 3  Placebo      1
#> 4  Placebo      1
#> 5  Placebo      4
#> 6 Low Dose      5

# Use apa.d.table function
table1 <- apa.d.table(iv = dose, dv = libido, data = viagra)


# Save Table 1 in a .doc document
apa.save(filename = "table1.doc", table1)


# Create a table for your PDF
# Include the lines below in your rmarkdown or Quarto document

#> \item \textit{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.
