Hi there,
I have been trying to use the "pvclust" package but have been having some difficulties. This is the first time I have used R so I am sure the mistake I am making is a basic one. The data I have is a distance matrix and I have been using the command; fit <- pvclust(cluster, nboot=1000, method.dist="euclidean") to try and perform hierarchical clustering with bootstrapped p-values, but I get the error message; Error in t.default(x) : argument is not a matrix. I guess there is a problem with the way the data is laid out, do you know how the data should be displayed in order to get the command to work (the data I am using I have pasted below), I have tried various methods of organising it!
