Installation

From Bioconductor

if (!requireNamespace("BiocManager", quietly=TRUE))
    install.packages("BiocManager")
BiocManager::install("sesameData")

Development version can be installed from github

Usage

sesameData package provides associated data for sesame package. It also maintains probe annotation for different Infinium platforms.

Each datum is accessible through the sesameDataGet interface which allows package level in-memory caching. For example, data can be retrieved with the title:
