-  #' Creating igraph graphs from adjacency matrices
-  #'
-  #' This function and all of its descriptions have been obtained from the igraph package.
-  #' @param adjmatrix A square adjacency matrix. From igraph version 0.5.1 this
-  #' can be a sparse matrix created with the Matrix package.
-  #' @param mode Character scalar, specifies how igraph should interpret the supplied matrix.
-  #' See also the weighted argument, the interpretation depends on that too.
-  #' Possible values are: directed, undirected, upper, lower, max, min, plus.
-  #' @param weighted This argument specifies whether to create a weighted graph from an adjacency matrix.
-  #' If it is NULL then an unweighted graph is created and the elements of the adjacency matrix gives the
-  #' number of edges between the vertices. If it is a character constant then for every non-zero matrix
-  #' entry an edge is created and the value of the entry is added as an edge attribute named by the weighted argument.
-  #' If it is TRUE then a weighted graph is created and the name of the edge attribute will be weight.
-  #' @param diag Logical scalar, whether to include the diagonal of the matrix in the calculation.
-  #' If this is FALSE then the diagonal is zerod out first.
-  #' @param add.colnames Character scalar, whether to add the column names as vertex attributes.
-  #' If it is ‘NULL’ (the default) then, if present, column names are added as vertex attribute ‘name’.
-  #' If ‘NA’ then they will not be added. If a character constant, then it gives the name of the vertex attribute to add.
-  #' @param add.rownames Character scalar, whether to add the row names as vertex attributes.
-  #' Possible values the same as the previous argument. By default row names are not added.

-  #' Creating igraph graphs from incidence matrices
-  #'
-  #' This function and all of its descriptions have been obtained from the igraph package.
-  #' @param incidence The input incidence matrix. It can also be a sparse matrix from the \code{Matrix} package.
-  #' @param directed Logical scalar, whether to create a directed graph.
-  #' @param mode A character constant, defines the direction of the edges in directed graphs,
-  #' ignored for undirected graphs. If ‘out’, then edges go from vertices of the first
-  #' kind (corresponding to rows in the incidence matrix) to vertices of the second
-  #' kind (columns in the incidence matrix). If ‘in’, then the opposite direction is used.
-  #' If ‘all’ or ‘total’, then mutual edges are created.
-  #' @param multiple Logical scalar, specifies how to interpret the matrix elements. See details below.
-  #' @param weighted This argument specifies whether to create a weighted graph from
-  #' the incidence matrix. If it is NULL then an unweighted graph is created and the
-  #' multiple argument is used to determine the edges of the graph. If it is a character
-  #' constant then for every non-zero matrix entry an edge is created and the value of
-  #' the entry is added as an edge attribute named by the weighted argument. If it is
-  #' TRUE then a weighted graph is created and the name of the edge attribute will be ‘weight’.
-  #' @param add.names A character constant, NA or NULL. \code{graph_from_incidence_matrix}
-  #' can add the row and column names of the incidence matrix as vertex attributes.
-  #' If this argument is NULL (the default) and the incidence matrix has both row
-  #' and column names, then these are added as the ‘name’ vertex attribute. If you want a different vertex attribute for this, then give the name of the attributes as a character string. If this argument is NA, then no vertex attributes (other than type) will be added.
-  #' @details Bipartite graphs have a ‘type’ vertex attribute in igraph, this is boolean
-  #' and FALSE for the vertices of the first kind and TRUE for vertices of the second kind.
-  #'
-  #' graph_from_incidence_matrix can operate in two modes, depending on the multiple
-  #' argument. If it is FALSE then a single edge is created for every non-zero element
-  #' in the incidence matrix. If multiple is TRUE, then the matrix elements are
-  #' rounded up to the closest non-negative integer to get the number of edges to
-  #' create between a pair of vertices.
