Build Status CRAN_Status_Badge

Opal R Client for the Opal data warehouse. Most of the web services of Opal can be reached by an opalr function: import/export, data dictionaries, projects, tables, resources, permissions, users, DataSHIELD profiles etc.

See opalr documentation.

Installation:

# install from CRAN
install.packages("opalr")

# or install latest development version
remotes::install_github("obiba/opalr")

Basic usage:

library(opalr)
o <- opal.login('administrator', 'password', url = 'https://opal-demo.obiba.org')

# assign a table (as a data.frame) to a R symbol
opal.assign(o, 'D', 'CNSIM.CNSIM1')

# perform R operations on the server side
opal.execute(o, 'summary(D$GENDER)')
opal.execute(o, 'summary(D$LAB_GLUC)')

opal.logout(o)
