Package: ProteinPCA Type: Package Title: Principal Component Analysis (PCA) Tool on Protein Expression Data Version: 0.1.0 Author: Paul Angelo C. Manlapaz [aut, cre] () Maintainer: Paul Angelo C. Manlapaz Description: Analysis of protein expression data can be done through Principal Component Analysis (PCA), and this R package is designed to streamline the analysis. This package enables users to perform PCA and it generates biplot and scree plot for advanced graphical visualization. Optionally, it supports grouping/clustering visualization with PCA loadings and confidence ellipses. With this R package, researchers can quickly explore complex protein datasets, interpret variance contributions, and visualize sample clustering through intuitive biplots.
