quick question at a very beginning attempt to calculating trophic position for multiple species using only one baseline.
Any suggestion about what to do if the function extractIsotopeData just does not recognize my baseline, hence doesn't allow to initialize the model?
Here it is the function i run, which does not give errors apparently:
LowList <- extractIsotopeData(Low, b1 = "Baseline", b2 = NULL,
baselineColumn = "FG", consumersColumn = "Spp",
groupsColumn = "Community",
d13C = "d13C", d15N = "d15N",
deltaN = simulated_TDF$deltaN,
deltaC = simulated_TDF$deltaC)
but here is an example of what i get when checking str(LowList ):
$ Diplo-Diplo:List of 6
..$ dNb1 : num(0)
..$ dCb1 : num(0)
..$ deltaN: num [1:15] 2.61 2.95 ...
..$ deltaC: num [1:15] 0.863 0.111 ...
..$ dNc : num [1:2] 5.13 9.37
..$ dCc : num [1:2] -20.2 -18.9
it's like if it doesn't recognize baseline values as numbers... or can it be related with the fact that i only have three values for the baseline? Is there a minimum of values the function requires to be recognized as baseline?
Thank you for any hint you can give me
