Dear All

I get following error in some of my datasets while using VGAM package.

Error in backsolve(Rmat, rinv) :
  singular matrix in 'backsolve'. First zero in diagonal [1057]

Kindly advise how to tackle this error.

My formula reads like this: vgam(cbind(list of species)~s()+s(),
binomialff(multiple.responses = TRUE,, bred = TRUE), Trace = TRUE, maxit =
TRUE)

Your kind response is highly appreciated.
