Hi again List, Well this time Im writing for a friend (really J). He needs to create a distance matrix based on an abundance matrix using the 1-Pearsons R index. Well I told him to look at the proxy package, but there is only Pearson Index. He needs it to perform a clustering. Well, as soon as he told me there proxy only had the Pearson index I thought: He could just do something like
>NewObject<-1-PearsonMatrixObject But I didnt tell him that because Im not sure its the same thing, and it probably will generate a strange cluster with the braches ends distant from the base He told me that Statistica 7.0 has this Index, but he doesnt own it. So Is there a way on R to do this correctly? Thanks for the attention. ___________________________________ MSc. <mailto:[EMAIL PROTECTED]> Rodrigo Aluizio Centro de Estudos do Mar/UFPR Laboratório de Micropaleontologia Avenida Beira Mar s/n - CEP 83255-000 Pontal do Paraná - PR - BRASIL Fone: (0**41) 3455-1496 ramal 217 Fax: (0**41) 3455-1105 [[alternative HTML version deleted]]
