Auxiliary function for burst()
burst_aux(x, labs = "V")A vector, matrix or data.frame (or a (pure) list, but that we don't use here)
The variable labels: - if NULL, no labels are used - if of length 1, use this label and append 1:ncol(x) but only if x doesn't have any column names (otherwise use the latter) - if of length ncol(x), use that but only if x doesn't have any column names (otherwise use the latter)
'x' as a list of named columns
- Performance critical (no checks here) - Data frames always have default names. They are possibly ugly but we have to use them here as we cannot determine whether they were assigned automatically or on purpose.
