I'm unable to get a some of autoplot behavior to work. Specifics below.

thought: Could be nice to be able to change the color scheme. That may be too feature-ful for autoplot, though.

@brookslogan Trying to document to regenerate the NAMESPACE. I'm hitting:

devtools::document()
ℹ Updating epiprocess documentation
ℹ Loading epiprocess
Error: 'archive_cases_dv_subset' is not an exported object from 'namespace:epiprocess'

Followed by:

devtools::document()
ℹ Updating epiprocess documentation
ℹ Loading epiprocess
Error in `withCallingHandlers()` at epiprocess/R/data.R:137:7:
! An error was raised while attempting to evaluate a promise (prepared
with `delayed_assign_with_unregister_awareness`) while an `unregister` or
`unregister_namespace` call was being evaluated. This can happen, for example,
when `devtools::load_all` reloads a package that contains a buggy promise,
because reloading can cause old package-level promises to be forced via
`pkgload::unregister` and `pkgload:::unregister_namespace`, due to
https://github.com/r-lib/pkgload/pull/157. If this is the current situation,
you might be able to be successfully reload the package again after
`unloadNamespace`-ing it (but this situation will keep re-occurring every
other `devtools::load` and every `devtools:document` until the bug or
situation generating the promise's error has been resolved).
Caused by error in `as.data.table()`:
! could not find function "as.data.table"
Run `rlang::last_trace()` to see where the error occurred.
