Hello I have a question about performing a similarity analysis using R. I will perform a similarity analysis comparing species. I have a datamatrix that looks like the Pictures you can see in the mail. It contains bivariate data and data in this Min Max mode. I had to alter the multivariate data into min max, because I had more than one number in one species and also I had to alter the unordered multivariate data into bivariate data for the same reason. Now I am looking for a similarity algorithm or approach in R that is able to deal with this data and further gives the possibility to weight the variables differently. By the way it would be fine if this approach would be also able to treat numerical data. I hope somebody can help me. Best regards Birgit ? ?
