I am trying to delete the rows in my dataset that has a U.S state name. I hope there is a way to input into the code without typing all 50 of them. Below I am sharing the big picture and where I would like to have these states input.

cshealthpredictors %>% 
 filter(!region %in% c("Alabama", "Arkansas" ,"Missouri","Texas","Georgia"))

As @Ritchie mentions in the comments there's a built in for that in base R.

state.name
