Hi!
I would like to calculate a constrained additive ordination with the package
VGAM. I get the error message:
Error in ncol(xbig.save) : object "xbig.save" not found
My data consists of 90 samples, 10 species and 3 environmental variables. The
species data is continous biomass data, with values from 0 to 3000 micrograms
per litre.
I use the function:
cao (name.of.species.matrix~Temp+LF+Ptot,
data=name.of.environmental.data.frame, family=gaussianff, df1.nl=3.5, Bestof=4)
After fitting model 1, I get an error message. Here is the output of model 1:
Obtaining initial values
Using initial values
Temp LF Ptot
lv 0.408 0.189 -0.77
Iteration 1
initial value 88934920.105286
iter 10 value 83029461.332581
iter 20 value 83028498.211367
final value 83028488.241532
converged
Error in ncol(xbig.save) : object "xbig.save" not found
I have tried it with fewer or more sites, fewer and more species, df1.nl from
0.5 to 5.5. I always get the same error message.
It only works when I use family=poissonff. But as I have continuous data, I
think I can't use poissonff.
Can anybody help me?
Thanks,
Romana
