plot_mediation: Plot mediation model with one or more mediators

In LukasWallrich/timesaveR: Functions to Accelerate (Academic) Data Analysis and Reporting

Plot mediation model with one or more mediators

Description

Returns graphViz code and graph for (multiple) mediation model. Coefficients and significance values for paths need to be provided, based on the format returned by run_moderation()

Usage

plot_mediation(
  IV,
  DV,
  Ms,
  data,
  digits = 2,
  coef_offset = length(Ms),
  filename = NULL,
  ind_p_values = FALSE
)

Arguments

IV	Character. Name of predictor
DV	Character. Name of dependent variable
Ms	Character vector. Names of mediator variables
data	Dataframe with coefficients and significance values. See details.
digits	Number of digits for rounding
coef_offset	Tibble with values to position mediators. If not provided, the function will align mediators automatically, which is unlikely to provide a well-aligned chart (except for cases when the offset has been explicitly implemented for that number of mediators, currently 1 and 3). However, the returned code can still be edited. See timesaveR:::.coef_offset_3 for an example of an offset tibble.
filename	If provided, graph will be saved as .svg file.
ind_p_values	Should significance stars be shown for indirect effects, based on pvalues passed in data? If FALSE, indirect effects with confidence intervals that do not include zero are bolded

Value

A list of a the graph and the associated code.

Examples

## Not run: 
# Estimate mediation model (usually with bootstraps > 1000!)

res <- run_mediation(ess_health, fltdpr, health, dosprt, agea, bootstraps = 50)

# Run plot command
plot <- plot_mediation(
  IV = "Frequency of  <br /> feeling depressed",
  DV = "Self-reported <br /> poor health", Ms = "Frequency of <br /> physical activity", 
  data = res
)

# Show the graph
plot$graph

# Show the code 
plot$code

# To create the graph again (e.g., after you edit its code)
DiagrammeR::grViz(plot$code)

## End(Not run)
