Tenta usar o %in% para reduzir os ifelse() (Não sei se é o caso, mas a
função SE() do excel tem limite encadeiamentos, pode ser o caso aqui
também)... Ex:
Todos esses ifelse()'s:
ifelse((origin=="am") & (destination=="ro"),1,ifelse((origin=="am") &
(destination=="rr"),1,ifelse((origin=="am") &
(destination=="pa"),1,ifelse((origin=="am") & (destination=="mt"),1
Podem ser substituido por:
ifelse(origin=="am" & destination %in% c("ro", "rr", "pa", "mt"),1,
ifelse(...))
E ainda assim acho que não é o mais adequado... Dependendo de como
estão os teus dados, eu usaria um merge() para resolver o problema

Boa noite!

fronteiras dos estados brasileiros. Porém, quando tendo rodar o R
reporta o seguinte erro:
Erro: estouro da pilha de contexto na linha 18
O que devo fazer?
