 This `R` package is a planning tool, designed to be used alongside other
 tools and sources of information about health datasets for research.

-If a researcher wants to access datasets within SAIL databank, how do
-they know which variables will represent the concepts they care about
-for their research question? For many health datasets, including SAIL,
-the metadata is publicly available. This `R` package uses the [Health
-Data Research
-Gateway](https://web.www.healthdatagateway.org/search?search=&datasetSort=latest&tab=Datasets)
-and the connected [Metadata
-Catalogue](https://modelcatalogue.cs.ox.ac.uk/hdruk_live/). This `R`
-package has a function which takes a metadata file as input and
-facilitates the process of browsing through each dataset and variable.
-The user is asked to categorise each variable into a domain related to
-their research question, and these categorisations get saved in a csv
-file for later reference. To speed up this process, the function
-automatically categorises some variables that regularly appear in health
-datasets (e.g. ID, Sex, Age).
