Create latent profile plots

Creates a profile plot for a single object of class 'mplus.model', or a faceted plot of profile plots for an object of class 'mplus.model.list'.

plotMixtures(
  modelList,
  variables = NULL,
  coefficients = c("unstandardized", "stdyx.standardized", "stdy.standardized",
    "stdy.standardized"),
  parameter = c("Means", "Intercepts"),
  ci = 0.95,
  bw = FALSE,
  rawdata = FALSE,
  alpha_range = c(0, 0.1)
)

Arguments

modelList	A list of Mplus mixture models, or a single mixture model
variables	A character vectors with the names of the variables (included in the Mplus output) to be plotted.
coefficients	Which type of coefficients to plot on the y-axis; default is 'unstandardized'. Options include: c('stdyx.standardized', 'stdy.standardized', 'std.standardized')
parameter	Which parameter to plot (from Mplus parameter estimate headings included in the output). Defaults to c('Means', 'Intercepts').
ci	What confidence interval should the errorbars span? Defaults to a 95% confidence interval. Set to NULL to remove errorbars.
bw	Logical. Should the plot be black and white (for print), or color?
rawdata	Should raw data be plotted in the background? Setting this to TRUE might result in long plotting times. Requires including the Mplus syntax 'SAVEDATA: FILE IS "filename"; SAVE = cprobabilities' in the Mplus input.
alpha_range	The minimum and maximum values of alpha (transparancy) for the raw data. Minimum should be 0; lower maximum values of alpha can help reduce overplotting.

Value

An object of class 'ggplot'.
