The variable hosp1 has 2 columns: Latitude and Longitude. We want to see if the pairs of data share a correlation, i.e. is there a relationship between Latitude and Longitude? Does increasing the first variable affect the second variable?
- A positive correlation means as Variable 1 increase Variable 2 increases
- A negative correlation means as Variable 1 increases Variable 2 decreases
- No correlation mean that increasing Variable 1 has no general effect on Variable 2
cor(hosp1$Latitude,hosp1$Longitude)  -0.1113144
So the function is
And hosp1$Latitude is the Latitude column and hosp1$Longitude is the Longitude column
