I have data for water temperature from two reservoirs taken over 5 years. I
want to match the water temperatures from the two reservoirs from samples
taken on the same day as not all samples were taken at the same time. I
therefore have four columns: 1) date of sample res 1; 2) nitrate res 1; 3)
date of sample res 2; 4) nitrate res 2.
There are uneven sample numbers for each reservoir where there was data
missing from one of the reservoirs.
Many thanks
