In OlinkAnalyze: Facilitate Analysis of Proteomic Data from Olink

Split the top matrix from Olink dataset in wide format.

Description

The function splits the top matrix df_top into chunks of columns, each of which contains separate information that will be combined with matching chunks from df_mid to convert the wide dataset into a long one.

Usage

read_npx_wide_top(df, file, olink_platform, format_spec)

Arguments

df	Top matrix of Olink dataset in wide format df_top.
file	Path to Olink software output file in wide format. Expected one of file extensions "xls", "xlsx", "csv", or "txt".
olink_platform	Olink platform used to generate the input file. One of NULL (default) for auto-detection, "Flex", "Focus", "Target 48", or "Target 96".
format_spec	A tibble derived from olink_wide_spec in the local environment containing the expected format of the Olink wide file based on the olink_platform and data_type.

Value

A list of data frames from top matrix in long format:

• Data frame containing Olink assays df_top_oid

• Data frame containing plate identifiers df_top_pid

• Data frame containing QC warnings df_top_qc_warn

• Data frame containing internal control assays df_top_int_ctrl

• Data frame containing deviation from internal control assays df_top_dev_int_ctrl
