General information

protGear is a package for protein micro-array data processing just before the main analysis.

The package loads the ‘gpr’ or ‘txt’ file format extracted by the quantification software and merges this with the specific sample identifiers. The package processes multiple files extracted in a batch with their corresponding sample identifier file. The sample identifier file has 2 variables ‘v1’ and ‘v2’ which indicate the mini-array or block number and sample identifier respectively. The ‘gpr’ file and the corresponding sample identifier file have the same file name. protGear also provides a web based Shiny(R) platform for real time visualization of the data processing.

There is a package vignette included with this package with a step by step use of the package. Check https://keniajin.github.io/protGear/ under articles.

Installing the devel package 

library(remotes) 
remotes::install_github("keniajin/protGear")
