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 fromx
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 aroundbase::sys.source
that defaults to sourcing in the current frame. -
attach_source()
andattach_eval()
: Evaluate an R script or expression in an attached environment -
within()
S3 methods for R environments.
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.
