Usage

vwc.tracebacks(vwc, type = "messages")

Arguments

AnalysisPageValueWithConditions

type

Type of conditions. Must be "messages", "warnings" or "error". Default: "messages". A (new) error is thrown if type is "error" but the vwc is not an error (that is, does not have an error, or more specifically, !vwc.is.error(vwc)).

Value

For "messages" or "warnings" it gives a list of Charvecs of tracebacks, as built by getTraceback. For "error" it only gives a single charvec, since there is only one error.
