readNonXYData {beadarray}R Documentation

Read BeadArray information into R

Description

Read csv files which contain bead-level data without x and y positions for each bead. An BeadLevelList can be created with limited functionality available or used to create an BeadSummaryList (bead summary data).

Usage

readNonXYData(files, max_length)

Arguments

files List of filenames to be read
max_length numeric value specifying the length of the longest file to be read

Details

This function can be used to read bead-level data generated by the Illumina scanning software but which does not contain the bead centre coordinates for each bead. Files of this type may have all undecoded beads removed from the output, hence a different number of beads may appear in each file. As matrices in R are required to have the columns of the same length we need to specify the length of the longest file to be read in to create a matrix large enough to hold the data.

The function creates an BeadLevelList containing foreground and ProbeID for each bead on each array

Value

BLData object with list components R and ProbeID
