A package to make R installed packages somewhat portable
Project description
rfile
Overview
rfile
generates an Rfile
to make your R package set reproducable, similar to
how Gemfile
and Brewfile
work.
Installing rfile
pip install rfile
Backstory
I'm not in the trenches every day with R, sometimes taking breaks of months at a
time from the language. When I arrive back, I'm often looking at previous code,
and trying to get back up to speed as quickly as possible. If I've updated all
of my package via brew
in the interim, I'm going to have a bad time with
missing packages. Having an Rfile
that knows about all the packages that I
previously had installed enables a quick recovery, and gets me back to stumbling
my way through the tidyverse
again!
Current Functionality
Currently, only reading and writing from the current directory is supported. The
default mirror for CRAN is http://cran.us.r-project.org
, which can be changed
by specifying -m/--mirror
.
Usage
rfile -h
usage: rfile [-h] [-m MIRROR]
Generate an Rfile for your packages
optional arguments:
-h, --help show this help message and exit
-m MIRROR, --mirror MIRROR
Enter a mirror to use for CRAN (default:
http://cran.us.r-project.org)
Generate an Rfile
rfile
will create an Rfile
with a list of installed packages in the currnet
working directory. This will cover both CRAN and Github packages. You can then
include this file in something similar to a "dotfiles" repository for easy
portability.
Install packages from an Rfile
Run rfile
in the same directory as the Rfile
. That's it.
