I am doing a PCA with R snippet in Knime:
rframe <- knime.in library("FactoMineR") res.pca=PCA(rframe,ncp=15, graph=F)
Then I am checking variable correlations with the axes:
d=dimdesc(res.pca, axes=c(1,2)) knime.in = data.frame(d$Dim.1$quanti) knime.out= knime.in
The problem: the output of the last node does not display variable names, just row number. So how can I associate a row number to a variable? I have as many rows as I have variables, but I don't know the sort order (if any). You'll find the ouptut in attachment.
