In KGodard1/Fastball-SourceCpp: Extracts the Backbone from Weighted Graphs

Description Usage Arguments Details Value Examples

'backbone.extract' returns a binary or signed adjacency matrix containing the backbone that retains only the significant edges.

backbone.extract(
  backbone,
  signed = FALSE,
  alpha = 0.05,
  fwer = "none",
  class = "original",
  narrative = FALSE
)

`backbone`	backbone: backbone S3 class object.
`signed`	Boolean: TRUE if signed backbone is to be returned, FALSE if binary backbone is to be returned
`alpha`	Real: significance level of hypothesis test(s)
`fwer`	string: type of familywise error rate correction to be applied; c("none","bonferroni","holm"). If "holm", Holm Bonferroni Family-wise Error Rate test is used, if "bonferroni", Bonferroni Family-wise Error Rate test should be used. By default, the given 'alpha' value is used for all tests with no correction for family-wise error rates.
`class`	string: the class of the returned backbone graph, one of c("original", "matrix", "sparseMatrix", "igraph", "network", "edgelist"), converted via tomatrix. If "original", the backbone graph returned is of the same class as the data used to generate the backbone object.
`narrative`	Boolean: TRUE if suggested text for a manuscript is to be returned.

The "backbone" S3 class object is composed of two matrices, a summary dataframe and (optionally, if generated by using fdsm) a 'dyad_values' vector. This object is returned by sdsm, fdsm, fixedrow, fixedcol, fixedfill.

The Holm Bonferroni correction was originally a port from python code written by Dr. Samin Aref. The authors thank Dr. Aref greatly for his contribution to this package!

backbone graph: Binary or signed backbone graph of class given in parameter 'class'.
