Using Leaflet, the map below pinpoints the stadium locations of California’s 16 minor league baseball teams. The map was generated using information provided by Baseball Pilgrimages.



Appendix


The above map is generated using the following code:

library(leaflet)

#read csv into r
minorParks <- read.csv(file = "parks.csv", 
                       header=TRUE, 
                       as.is = TRUE,
                       stringsAsFactors = FALSE,
                       sep = ',')
#the 'head' command is not necessary for the code to work, but here is used to give the user an exploratory feel for the underlying dataframe
head(minorParks, 3)
