Fw: Summary for Distance matrix by cosine?
...ver I had to transpose the matrix first, for I want to calculate the distance of the _rows_. Regards, Petra Steiner #Funktion: Berechnung der Distanzmatrix mit dem Kosinus als Abstandsmass library(Matrix) normalize <- function(ma) { # zunaechst werden die Zeilen der Matrix normalisiert nreihe <- nrow(ma) nspalte <- ncol(ma) print(nspalte) c <- matrix(NA, nreihe, nspalte) row.names(c) <- row.names(ma) colnames(c) <- colnames(ma) for (i in 1:nreihe) { print(i) normrow <- norm(ma[i,],"F") for (j in 1:nspalte) { c[i,...
