I wonder to class my data based on A+B. but when plotting the figure, I want to legend A and B separately. Like, A by color, B by pch. Is that possible? Thanks.

    Hi there,

    I'm not sure what you want to do, but you can have two legends using plotIndiv, one for the color and one for the pch:

    X <- breast.tumors$gene.exp
    Y <- breast.tumors$sample$treatment
    splsda.breast <- splsda(X, Y,keepX=c(10,10),ncomp=2)
    plotIndiv(splsda.breast, ind.names = FALSE, pch = c(3,4,2), legend=T)


    X <- liver.toxicity$gene
    Y <- liver.toxicity$clinic
    toxicity.spls <- spls(X, Y, ncomp = 3, keepX = c(50, 50, 50),
    keepY = c(10, 10, 10))
    plotIndiv(toxicity.spls, 'X-variate',
    group = liver.toxicity$treatment[, 'Time.Group'],
    ind.names = FALSE,
    legend = TRUE,pch=c(1,2,3))
