The goal of {epidict} is to provide standardized data dictionaries for use in epidemiological data analysis templates. Currently it supports standardised dictionaries from MSF OCA. This is a product of the R4EPIs project; learn more at https://r4epi.github.io/sitrep/
You can install {epidict} from CRAN:
If there is a bugfix or feature that is not yet on CRAN, you can install it via the {drat} package:
You can also install the in-development version from GitHub using the {remotes} package (but there’s no guarantee that it will be stable):
The dictionaries can be obtained via the msf_dict()
function, which specifies a variable and their possible options (if
categorical).
There are MSF intersectional outbreak dictionaries available in {epidict} based on ODK exports.
There are MSF OCA outbreak dictionaries available in {epidict} based on DHIS2 exports. > You can read more about the outbreak dictionaries at https://r4epi.github.io/epidict/articles/Outbreaks.html
In addition, there are MSF survey dictionaries available based on ODK exports. > You can read more about the survey dictionaries at https://r4epi.github.io/epidict/articles/Surveys.html
You can also read in your own ODK dictionaries using
read_dict().
The {epidict} package has a function for generating data that’s
called gen_data(), which takes three arguments: The
dictionary, which column describes the variable names, and how many rows
are needed in the output.
