usefuldata

The usefuldata package provides useful datasets for analysis. It currently includes pre-processed mapping datasets for Olink and SomaLogic proteomics platforms, but will include other datasets in the future.

Installation

You can install the package from GitHub using the remotes package:

# install.packages("remotes")
remotes::install_github("mattlee821/usefuldata")

Datasets

The package contains the following datasets:

1. mapping_GRCh38_p14_olink

This dataset maps Olink proteins (UniProt IDs) to gene identifiers and genomic positions.

Columns include:

• UNIPROT: UniProt ID (Olink identifier)
• Target: Gene Symbol
• ensembl_gene_id: Ensembl Gene ID
• hgnc_id / hgnc_symbol: HGNC info
• START_hg19 / END_hg19: Genomic coordinates (hg19)
• START_hg38 / END_hg38: Genomic coordinates (hg38)

2. mapping_GRCh38_p14_somalogic

This dataset maps SomaLogic aptamers (SeqId/SomaId) to gene identifiers and genomic positions.

Columns include:

• SeqId: Sequence ID
• SomaId: SomaLogic ID
• UNIPROT: UniProt ID
• Target: Gene Symbol
• ensembl_gene_id: Ensembl Gene ID
• START_hg19 / END_hg19: Genomic coordinates (hg19)
• START_hg38 / END_hg38: Genomic coordinates (hg38)

Usage

You can load the datasets directly into your R session:

library(usefuldata)

# Load Olink mapping
head(mapping_GRCh38_p14_olink)

# Load SomaLogic mapping
head(mapping_GRCh38_p14_somalogic)
