Boa noite pessoal,
Estou criando um pacote e dentro de uma função desse meu pacote estou usando uma função chamada NbClust de um pacote também chamado NbClust, que me gera um número ótimo de clusters dado o input que forneço.
O que acontece é que essa função do NbClust, apesar de eu pedir para que salve o resultado num objeto, ele gera vários gráficos e mensagens que eu gostaria que fosse omitido, pois o que eu preciso está dentro do objeto criado.
Há uma maneira que eu possa silenciar/impedir a geração desses gráficos e mensagens?
Segue um exemplo reprodutível:
df <- tibble::tribble(
~name, ~axis_1, ~axis_2,
"A", -154.9610, 59.47976,
"B", -153.3270, 61.49629,
