The R package requiRements provides the ability to install all packages provided in a text or given a raw string. This is meant to simply keep all e.g project dependent packages in one file (like the demo requirements.txt within ./data-raw/requirements.txt) and install them all in a rush by using requiRements::install("./requirements.txt").

This is well known from python and now available within R.


You can install requiRements directly from CRAN:


The development version can be installed using

devtools::install_github("joundso/requirements", ref = "development")

Basic functions

Install some packages providing a single string

## Test it with a string:
demo_string <- "
# this_one_will_be_ignored
requiRements::install(packages = demo_string)

Install some packages providing a string vector

## Test it with a vector:
demo_vec <-
    "# this_one_will_be_ignored"
requiRements::install(packages = demo_vec)

Install some packages providing a file containing the packagenames

## Test it with a file:
demo_path <- "./data-raw/requirements.txt"
requiRements::install(path_to_requirements = demo_path)

Install some packages with a string AND a file

:bulb: Using the above defined variables demo_string, demo_vec and demo_path:

## Test it with a string AND a file:
requiRements::install(packages = demo_string,
                      path_to_requirements = demo_path)

## Test it with a vector AND a file:
requiRements::install(packages = demo_vec,
                      path_to_requirements = demo_path)
