Warning messages:
1: Removed 31 rows containing missing values (geom_text).
2: The vignette title specified in \VignetteIndexEntry{} is different from the title in the YAML metadata. The former is "fortedata: Utilities and Examples", and the latter is "fortedata: Working with the data". If that is intentional, you may set options(rmarkdown.html_vignette.check_title = FALSE) to suppress this check.
