sysreqs is a database of system requirements mappings for installing and running R packages on various operating systems.
R packages may specify
SystemRequirements in their
files to list software that must or should be installed on the
system to use the package. This is not a standardized field,
and various packages specify the same system requirements differently.
sysreqs is a hand-curated database of the
entries, and their resolutions on various operating systems. The
data itself is stored in a GitHub repository, at
https://github.com/r-hub/sysreqs, and its public API is at
