    Bonjour,

    je voudrais poser une autre question sur MCOA s'il vous plait,

    If I run mcoa on 3 datasets with equal nrow but unequal ncol, the
    options "lambda1" and "uniform" are ok but option= "inertia" fails.
    Should I expect this?

    mcoa(testdata$ktab, option="lambda1")
    mcoa(testdata$ktab, option="uniform")
    mcoa(testdata$ktab, option="inertia")
       Error in La.svd(x, nu, nv) : error code 1 from Lapack routine dgesdd

    If I run the analysis on a dataset with equal nrow, ncol. I don't get
    the error with option="inertia".

    Is this expected?

    Merci
    Aedin

    talking to the many French supporters in Dublin at the weekend???)
