pepr is an R package for reading Portable Encapsulated Projects, or PEPs, in R. If you describe your project (configuration and samples) according to this format, you can load all project metadata into R using the pepr package. To test pepr, you can try loading one of the example PEPs.

Complete documentation and API for the pepr R package is at code.databio.org/pepr.

Install from CRAN:

install.packages("pepr")

Load a project and explore metadata like this:

library("pepr")
cfgPath = system.file(
    "extdata",
    "example_peps-master",
    "example_basic",
    "project_config.yaml",
    package = "pepr"
  )
p = Project(file = cfgPath)

sampleTable(p)
config(p)
