Returns a vector of worst-performing nodes (by error)

1 2	badnodes(valdata, variable = "width", n = 4, which = c("abs", "min", "max"), standardize = FALSE)

`valdata`	As returned by `rt_valdata()`
`variable`	Which variable's errors define "bad" nodes?
`n`	Number of bad nodes to return
`which`	"abs" for worst absolute errors, "min" for worst negative errors, "max" for worst positive errors
`standardize`	scale by estimated uncertainty? Default is `FALSE`.
