Ana, pelo jeito que os teus dados estão impressos o R está lendo os números como texto (provavelmente eles possuem um ponto como separador de milhar, tem que tirar eles). Outro erro é como o R está interpretando o $DoseT-3 para carregar a coluna, ele está procurando a variavel DoseT e subtraindo 3 dela, acho que colocando entre aspas ("$DoseT-3") resolva. Tu pode fazer direto: wilcox.test(dados$"DoseT-3", dados$"DoseT+3", paired=TRUE) pois não há a necessidade de tirar as colunas que tu não vai utilizar, uma vez que tu chama as que tu vai utilizar. 2013/6/20 <alanarocha@sapo.pt>
