as bordas default do grafico sao muito grandes para 18 fgrádicos de forma que nao sobra área util experimente fazer antes algo como par(mfrow=c(6,3), mar=c(2.5, 2.5,0.1,0.1), mgp=c(1.6, 0.7, 1)) (mude os valores acima para melhor visualizacao) help(par) te explica "mar" e "mgp" em datales, mas estes controlam as margens de cada gráfico e a distancia das anotacoes aos eixos On Wed, 13 Jun 2012, Ricardo Dobrovolski wrote:

Oi Pessoal, Eu quero plotar 18 gráficos de dispersão.

No entanto, eu tive a seguinte mensagem de erro:

"Erro em plot.new() : margens da figura muito grande"

Os comandos que utilizei são os seguintes:

onde agro.gdp e agro.hdi são duas tabelas de dados e os termos entre aspas representam nomes das minhas colunas.
