PlotVar with only one Y

[Former user]

Hello, I have no problem when I use plotvar() after a pls() with many Y (Fig.1). But if i do this with only one Y,I get the Fig.2 (the name of the variable disappears). How could I fix it? Thank you for your answer

Hi there,

The input parameter "var.names" should do the trick:

data(liver.toxicity)
X <- liver.toxicity$gene
Y <- liver.toxicity$clinic[,1]
toxicity.spls <- spls(X, Y, ncomp = 3, keepX = c(50, 50, 50))
plotVar(toxicity.spls) # your problem is here
plotVar(toxicity.spls,var.names=list(X=colnames(X),Y="bla")) # name of Y is now "bla"
