envir

envir is a small R package with a handful of functions designed for managing R environments.

The main exported functions are:

• import_from(x, ...): Import objects from x into the current environment. x can be:

  • A package name
  • Filepaths to R scripts
  • Any object with names and [[ methods.

  Usage example:

  import_from(magrittr, `%<>%`, `%>%`)
  import_from(dplyr) # all exported functions
  import_from("my_script.R", useful_function)

  See ?import_from for extended usage examples.

• include(): A vectorized wrapper around base::sys.source that defaults to sourcing in the current frame.

• attach_source() and attach_eval(): Evaluate an R script or expression in an attached environment

• within() S3 methods for R environments.

Installation

You can install the released version of envir from CRAN with:

install.packages("envir")

Or install the development version with:

if (!requireNamespace("remotes", quietly = TRUE)) 
  install.packages("remotes")
remotes::install_github("t-kalinowski/envir")

R has excellent support for managing environments already, but some of the defaults encourage usage patterns that don’t scale well to larger code bases.

Other solutions developed for managing R environments:

• modules
• import
• box

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
