Boa noite amigos do R, Estou precisando de uma ajuda para plotar uma figura! Na verdade é algo bem simples, pois preciso somente plotar meus dados médios e o desvio padrão. O grande problema é que quando uso o pacote gplots ele não mantem a proporção no eixo x, o que acaba distorcendo os dados. Abaixo tem uma tentativa minha usando a função "plot", mas ainda não consegui uma saída pra plotar a média + desvio padrão. Por acaso alguém tem uma solução????
