[R-sig-eco] How to handle Inf values in VGAM

[Rajendra Mohan Panda]

Dear All

I thank you all for your response and making this forum a 'knowledge hub'.
I have immensely benefited from this forum scientists. This time the error
is on handling infinite values in VGAM model run. Because of infinite
values, I get following errors:

VGAM  s.vam  loop  1 :  loglikelihood = -6516.0523
VGAM  s.vam  loop  2 :  loglikelihood = -Inf
Error in s.vam(x, z, wz, tfit$smomat, which, tfit$smooth.frame, bf.maxit,
 :
  NA/NaN/Inf in foreign function call (arg 4)

I use following formula for my model:

vgam(cbind(species.list) ~s(hanpp), data = SPEV, binomialff(link = "logit",
multiple.responses = TRUE, bred = TRUE), maxit = 100,trace = TRUE)

N.B. Species data format includes only 0 or 1  with no NA or missing values

 Kindly advise if there is any way to check this error prior to model run
or during the modelling process.

Your kind response is highly appreciated
