Thank you so much, FJCC. STRINGR was loaded but when I re-installed it, it seems as though it became unloaded. I didn't see what package str_view_all was a part of in the help documentation (it is there in small italic text), and I assumed it was a part of the htmlwidgets package. I need to remember that all anything that begins with str is a part of the stringr package.
Thank you so much. I hadn't loaded the stringr library, and you figured out my 2nd problem which was my original problem before I uninstalled and re-installed my stringr package.
