documentation of plot_bivariate

[jrosen48]

Per (closing) #146, I did a (perhaps not recommended in most cases, but perhaps warranted in this case) hard reset to 791b33d, which was the commit associated with #141.

When I create a branch from master, which is at the above SHA, and run devtools::document(), I see the following error:

devtools::document()
Updating tidyLPA documentation
Updating roxygen version in /Users/jrosenb8/tidyLPA/DESCRIPTION
Writing NAMESPACE
Loading tidyLPA
tidyLPA is intended for academic use. We do not make any money on this and only ask that you please cite this in publications when you use the results. You can use the function citation('tidyLPA') to create a citation.Mplus is not installed. Use only package = 'mclust' when calling estimate_profiles().
Error in get(name, envir = asNamespace(pkg), inherits = FALSE) : 
  object 'wrapString' not found
Warning: [TEMPLATE:2] @usage requires a value
Error: Result 18 must be a single string, not NULL of length 0
Run `rlang::last_error()` to see where the error occurred.
In addition: Warning message:
In structure(x, class = "rd") :
  Calling 'structure(NULL, *)' is deprecated, as NULL cannot have attributes.
  Consider 'structure(list(), *)' instead.  
```{}

I can't tell if this is due to using Roxygen `7.0.2`, whereas I believe the last set of docs were created using version 6, or something else. Perhaps not a big deal, but kind of a pain in the butt if I need to update the docs.

still getting this issue.

To see whether I introduced it, I checked out the repository at the stage of @cjvanlissa your last major commit (791b33d15b8eb9ba05424cb94fbd87d45a92c32c - this was 25 days ago today), e.g.:

git checkout 791b33d15b8eb9ba05424cb94fbd87d45a92c32c

I still get this same message. Any idea what's up @cjvanlissa ?

closing this in light of #151
