Plot global graph measures across densities

Description

Create a faceted line plot of global graph measures across a range of graph densities, calculated from a list of brainGraphList objects. This requires that the variables of interest are graph-level attributes of the input graphs.

Usage

plot_global(g.list, xvar = c("density", "threshold"), vline = NULL,
  level.names = "default", exclude = NULL, perms = NULL,
  alt = "two.sided")

Arguments

`g.list`	List of `brainGraphList` objects; the length of this list should equal the number of thresholds/densities in the study
`xvar`	A character string indicating whether the variable of interest is “density” or “threshold” (e.g. with DTI data)
`vline`	Numeric of length 1 specifying the x-intercept if you would like to plot a vertical dashed line (e.g., if there is a particular density of interest). Default: `NULL`
`level.names`	Character vector of variable names, which are displayed as facet labels. If you do not want to change them, specify `NULL`. By default, they are changed to pre-set values.
`exclude`	Character vector of variables to exclude. Default: `NULL`
`perms`	A `data.table` of permutation group differences
`alt`	Character vector of alternative hypotheses; required if perms is provided, but defaults to “two.sided” for all variables

Details

You can choose to insert a dashed vertical line at a specific density/threshold of interest, rename the variable levels (which become the facet titles), exclude variables, and include a brainGraph_permute object of permutation data to add asterisks indicating significant group differences.
