MetaPR2 is a database of published 18S rRNA metabarcodes that have been reprocessed and assigned using PR2.
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.
- Launch in your browser: http://shiny.metapr2.org
- Help : https://pr2database.github.io/metapr2-shiny/articles/
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')
metapr2::run_app()
Extensive help is provided here.
Please report errors in the Issues page of the metaPR2 database.
