ReadMPX_arrow_edgelist(pxl_file, edge_list_file = NULL, verbose = TRUE, ...)

Arguments

pxl_file: Path to a .pxl file
edge_list_file: Path to the output edgelist.parquet file
verbose: Print messages
...: Parameters passed to other methods

Value

Nothing. The edgelist is saved to a parquet file set with edge_list_file

Examples

library(pixelatorR)

# Load example data
pxl_file <- system.file("extdata/five_cells",
                        "five_cells.pxl",
                        package = "pixelatorR")
edgelist_arrow <- ReadMPX_arrow_edgelist(pxl_file)
