Add direct labels to a grouped lattice plot. This works by parsing the trellis object returned by the high level plot function, and returning it with a new panel function that will plot direct labels using the specified method.
# S3 method for trellis
direct.label(p, method = NULL, debug = FALSE)
The lattice plot (result of a call to a high-level lattice function).
Method for direct labeling as described in
