Dear members,

I am experiencing a strange error using the dredge function of the package MuMIn. I am not sure what is happening here as this script worked in the past and I have no idea about this new error, I do not have any NA in my data.

> full_m<- gam(nep~ s(depth, k=4) + s(sed, k=4) + s(slope, k=4) + s(vrm, k=4), family=gaussian, gamma=1.4, data = datafit_aran1)
> dredge(full_m)

Error in dredge(full_m) :
  'global.model''s 'na.action' argument is not set and options('na.action') is "na.omit"

Can anyone help me?

Thank you very much in advance,
