I often write dplyr code like the following. It would be nice if--after typing the function (mutate, select, etc.)--intellisense knew to look inside the dataframe IncGeo_Final for the suggested code completion.
Intellisense also doesn't seem to prioritize tidyverse functions after the maggitr. For example, if you added a maggitr to the above coded and started typing select or arrange, the tidyverse functions don't show up at the top of the listing.
Two suggestions:
IncGeo_Final <- IncGeo_Final %>% rename(ZipCode = IncidentZipCode) %>% mutate(ZipCode = gsub("-.*", "", ZipCode))
