I need the package MCA in order to run the following
mca1 = MCA(testscores, graph = FALSE)
However when I try to install this package in CRAN I find only MCAvariants package which I do not need. Any help for this?
Also I am trying to design in R a perceptual map. However the biplot function does not produce a good result. Any other package in order to design a perceptual map?
Many thanks in advance.
