I am trying to use featurePlot
of caret
in R.
This is the code I am using:
trellis.par.set(theme = col.whitebg(), warn = FALSE)
caret::featurePlot(x = df[, 3:6],
y = df$ud,
plot = "scatter")
where all the columns of df[, 3:6]
are of numeric type, while df$ud
is a binary factor.
I also have installed the library ellipse
as suggested elsewhere.
However, I keep getting NULL
.
Any idea why?
