Hi Everyone,
I am a graduate student who will be using R to do my analysis. I need to do
a spatial analysis, and the first step is to calculate the geographic
distance between my study sites. I am hoping to use earth.dist because it
allows for multiple pairwise distances to be calculated at one time. I have
done a sample calculation, and I seem to have a problem between the steps of
using create.lats and earth.dist. I've copied the steps I've taken in R
since I am NOT computer literate and have a real problem debugging computer
programming. Hopefully someone can help.
create.lats(weatherstations,loc="locality",long="longitude",lat="latitude")
longitude latitude
Adra -119.58 49.73
Bankier Chain Lake -120.28 49.70
Chute Lake -119.53 49.68
Douglas Lake -120.20 50.16
Hedley -120.08 49.36
Hedley NP Mine -120.02 49.37
