Dear All, It's Eszter from Hungary, a total beginner with R. My problem is the following:
I have a dataset with binary values as a comma separated textfile. The samples are in the coloumns and the species are in the rows. I have to transpose it for the further PCoA analysis. There is no problem with reading the dataset. When I transpose the dataset, the original values become strings (instead of 0,1,0,0,1 I have "0","1","0","0","1"). The distance matrix cannot be counted from the transposed dataset, I have 2 error messages: <Warning in vegdist(tdf1, method = "jaccard", binary = FALSE, diag = FALSE, : results may be meaningless because input data have negative entries> <Error in rowSums(x, prod(dn), p, na.rm) : 'x' must be numeric> I do not understand the first, since I have only 1 and 0 in the dataset. I guess I have the second because of the strings instead of values in the dataset. Could you please help me solving these problems? I could not find anything about these in the manuals. Thank you, cheers: Eszter p.s. This is a new problem, last week I worked with a similar dataset and I did not get any error message like these. _____________________________________________________________________ Menő csengőhangok (MP3 is!) és színes képek a mobilodra.
