California Colleges
Now it is your turn to map all of the colleges in a state. In this exercise, we'll apply our example of mapping Maine's colleges to California's colleges. The first step is to set up your data by filtering the ipeds data frame to include only colleges in California. For reference, you will find how we accomplished this with the colleges in Maine below.
maine_colleges <-
ipeds %>%
filter(state == "ME")
maine_colleges
# A tibble: 21 x 5
name lng lat state sector_label
<chr> <dbl> <dbl> <chr> <chr>
1 Bates College -70.20333 44.10530 ME Private
2 Bowdoin College -69.96524 43.90690 ME Private
