In DataPackageR: Construct Reproducible Analytic Data Sets as R Packages

knitr::opts_chunk$set(echo = TRUE)

This file is processed second in the config.yml file. It therefore has access to the data objects created by subsetCars.Rmd, the file that is processed first in the config.yml.

Reading objects from previously run files

In order to read previously processed objects, we use the datapackager_object_read() API from DataPackageR:

library(DataPackageR)
cars_over_20 = datapackager_object_read("cars_over_20")
print(cars_over_20)

This API reads from an environment named ENVS, containing subsetCars and any other previously built data set objects. It is passed into the render environment of extra.rmd by DataPackageR at the render() call.

Additional data objects

This file will add the pressure data set to the example.

data(pressure)
pressure <- pressure # need to do an assignment
plot(pressure)
