Presentation

MetaPR2 is a database of published 18S rRNA metabarcodes that have been reprocessed and assigned using PR2.

Acessing the database

Access to the database to map, search and download the barcodes can be done in three different ways:

  • Using a web interface.

  • Download the R package and launch the shiny application.

1 - Web interface

2 - metaPR2 shiny R package

Install the package from GitHub
install.packages(devtools)

devtools::install_github("pr2database/metapr2-shiny")

Note: You may have to install some packages required by metapr2 if they are not installed on your machine

Alternatively install from R-universe

No need in this case to install package devtools

# Enable repository from pr2database
options(repos = c(
  pr2database = 'https://pr2database.r-universe.dev',
  CRAN = 'https://cloud.r-project.org'))

# Download and install metapr2 in R
install.packages('metapr2')
Launch shiny interface with function run_app()
metapr2::run_app()
