plot_ddsc {multid}

Plot deconstructed difference score correlation

Description

Plots the slopes for y1 and y2 by x, and a slope for y1-y2 by x for comparison.

Usage

plot_ddsc(
  ddsc_object,
  diff_color = "black",
  y1_color = "turquoise",
  y2_color = "orange",
  x_label = NULL,
  y_labels = NULL,
  densities = TRUE,
  point_alpha = 0.5,
  dens_alpha = 0.75,
  col_widths = c(3, 1),
  row_heights = c(2, 1, 0.5),
  coef_locations = c(0/3, 1/3, 2/3),
  coef_names = c("b_11", "b_21", "r_x_y1-y2")
)

Arguments

ddsc_object

An object produced by ddsc_sem function.

diff_color

Character. Color for difference score (y1-y2). Default "black".

y1_color

Character. Color for difference score component y1. Default "turquoise".

y2_color

Character. Color for difference score component y2. Default "orange".

x_label

Character. Label for variable X. If NULL (default), variable name is used.

y_labels

Character vector. Labels for variable y1 and y2. If NULL (default), variable names are used.

densities

Logical. Are y-variable densities plotted? Default TRUE.

point_alpha

Numeric. Opacity for data points (default 0.50)

dens_alpha

Numeric. Opacity for density distributions (default 0.75)

col_widths

Numeric vector. Widths of the plot columns: slope figures and density figures; default c(3, 1).

row_heights

Numeric vector. Heights of the plot rows: components, difference score, slope coefs; default c(2, 1, 0.5).

coef_locations

Numeric vector. Locations for printed coefficients. Quantiles of the range of x-variable. Default c(0, 1/3, 2/3).

coef_names

Character vector. Names of the printed coefficients. Default c("b_11", "b_21", "r_x_y1-y2").

Examples

set.seed(342356)
d <- data.frame(
  y1 = rnorm(50),
  y2 = rnorm(50),
  x = rnorm(50)
)
fit<-ddsc_sem(
  data = d, y1 = "y1", y2 = "y2",
  x = "x"
)

plot_ddsc(fit,x_label = "X",
          y_labels=c("Y1","Y2"))
