Hello,
I am struggling to remove the effect of distance in the similarities of species
composition between sites with the similarities of temperature between sites.
Example: i have 4 columns (a column : sites name, b: species similarities
between the two sites, c: environmental similarities between the two sites, and
d: distance between the two sites
Site A & site B, 0.34, 0.12, 2meter
site A & site C, 0.56,0.45, 0.5meter
Sites B &C, 0.76, 0.21, 0.98meter
Sites D &A, 0.56, 0.76, 1.5meter
Sites D & B, 0.01, 0.34, 7meter
Sites A & D, 0.98, 0.78, 2 meter
(note: , represents column)
Here i want to fit the data to a general linear model in which the similarities
values of the temperature variables calculated for each sites pair will be the
independent observations and the respective correlation coefficients of species
similarities will be the dependent observation. But I could not figure out how
to control the effects of distance between each sites pair. How can I calculate
it in R? Could you please help me?
