The goal of yum is to provide a number of functions to work with files that contain one or more YAML fragments. Several packages (the rock, dct, and justifier packages) leverage the YAML format to facilitate systematic encoding of information in a format that is both machine- and human-readable. The yum package provides a number of functions to facilitate this in a uniform manner with minimal dependencies (i.e. only suggests the yaml and data.tree packages to enable additional functionality).
You can install the released version of yum from CRAN with:
install.packages("yum");You can install the development version of yum from GitHub with:
devtools::install_github("matherion/yum");(assuming you have devtools installed; otherwise, install that first using the install.packages function)
yum was created to have minimal dependencies. However, you will usually want to have either [yaml::yaml] or [data.tree::data.tree] available to be able to actually load (parse) the extracted YAML fragments and organise them in a tree if they have a hierarchical structure. Therefore, yum does have some dependencies through those two suggested packages. Of these, yaml only has one dependency, but data.tree has a few more. Specifically, the dependency network looks like this:
