Design an R package vignette
This document is the vignette skeleton dist_conversion.Rmd created in the last exercise. It includes the most familiar parts of an R Markdown document:
- A YAML header that contains some metadata
- Narrative text written in Markdown
- R code chunks surrounded by
```{r}and```; a syntax that comes from theknitrpackage
To develop package documentation for the unitConverter package, it is vital to show users many different ways to work with the functionality of the package. Vignettes serve that purpose in both showing examples and also adding explanatory text and clarifications in an easy-to-read format.
