Read an MPX data item

ReadMPX_item reads any number of items from a .pxl file. If multiple items are specified, the output is a list of tbl_df objects. Otherwise the output is a single tbl_df. ReadMPX_polarization, ReadMPX_colocalization and ReadMPX_edgelist are wrappers for ReadMPX_item to read specific items.

Usage

ReadMPX_item(
  filename,
  items = c("colocalization", "polarization", "edgelist"),
  verbose = TRUE
)

ReadMPX_polarization(filename, verbose = TRUE)

ReadMPX_colocalization(filename, verbose = TRUE)

ReadMPX_edgelist(filename, verbose = TRUE)

Arguments

filename

Path to a .pxl file

items

One or several of "colocalization", "polarization", "edgelist"

verbose

Print messages

Value

Either an object of class tbl_df or a list of tbl_df

objects if multiple items are selected
