Questions for "domist... subscript out of bounds"
...R.
I faced a questions about subscript out of bounds.
Although I checked some other helps before I sent this email, I still don't know
how to deal with this problems.
I want to use "domain" function to run species distribution model in R.
I used "sp.occ.do<-domain(env.pre, pred_train, factors=c('continent')) &
sp.occ.pre.pro<-predict(env.pre, sp.occ.do)" to predict species distribution.
BUT, I got "Error in domdist(object, ln[j], vals[, ln[j]]) : subscript out of
bounds" and could not run the domain model.
How can I solve this problem?
Thanks,...
