readcern

Overview

This is a utility package for reading columnar file formats found at CERN. It provides support for reading over the XRootD protocol.

Installation

Currently readcern is only on GitHub.

devtools::install_github("rmatev/readcern")

Usage

Reading over XRootD

connection <- readcern::xrd('root://eosuser.cern.ch//eos/user/r/rmatev/readcern/README')
readr::read_file(connection)

Compressed files (.gz, .bz2 and .xz) are also supported.

Reading data from the accelerator logging database

read_acclogging_csv(readcern_example('Summary_4691_B1.HYB.CSV.gz'))

Reading PVSSExport data

PVSSExport is an LHCb-specific tool that writes out data in csv format. A thin wrapper arround read_csv is provided to read them:

readcern::read_pvss_export('root://eosuser.cern.ch//eos/user/r/rmatev/readcern/pvss.csv')
