A-node projection — edgelist_to_simple_Anode

A function to create an A node projection graph from an edgelist representing a bipartite graph.

Usage

edgelist_to_simple_Anode_graph(object, ...)

# S3 method for data.frame
edgelist_to_simple_Anode_graph(
  object,
  components = NULL,
  cl = NULL,
  verbose = TRUE,
  ...
)

# S3 method for FileSystemDataset
edgelist_to_simple_Anode_graph(object, components = NULL, verbose = TRUE, ...)

Arguments

object: An object containing an edgelist
...: Not yet implemented
components: Components to compute A node projection for
cl: A cluster object created by makeCluster, or an integer to indicate number of child-processes (integer values are ignored on Windows) for parallel evaluations. See Details on performance in the documentation for pbapply. The default is NULL, which means that no parallelization is used.
verbose: Print messages

Value

An A-node-projected graph

Examples


library(pixelatorR)
library(tibble)

#> Attaching package: ‘tibble’
#> The following object is masked from ‘package:igraph’:

#>     as_data_frame

pxl_file <- system.file("extdata/five_cells", "five_cells.pxl", package = "pixelatorR")

# Load edgelist
el <- ReadMPX_arrow_edgelist(pxl_file)
#> ℹ Extracting edgelist.parquet file to /var/folders/gw/bdcqhnvs0m9gs_mq8n51jtbc0000gn/T/RtmpJCnvFY/edgelist.parquet
#> ✔ Returning FileSystemDataset

# Convert to tbl_df
el_tbl_df <- as_tibble(el)
