Can someone help me with creating a map in R? I need to make a map of the number of retail stores a company has in each state. All I need is the store count displayed in each state.
For example: if there are 150 stores in California and 250 in Texas, I need the map to display 150 within the California borders and 250 within the Texas borders.
I created a map with:
m = map("states", region = c('Alabama', etc....))
I tried adding the numbers as a label but that didn't work.
m = map("states", region = c('Alabama', etc....), labels = c('24','56',etc....))
I must be missing something. I have a .csv file with the state name and the number of stores in each state. Is there an easy way to translate this into a graph? I'd like to avoid doing it by hand in Excel.
Thanks! That worked. Does anyone know how to deal with the labels that do not fit within a states boarders? Also, does anyone know how to color code states based on the number value? The image of the map and code I am using is below:
library("maps")
map.text("state", regions=c("alabama",
