DotBracketDataFrame object is derived from the
DataFrame class. The
DotBracketDataFrameList is implemented analogous, which is also
CompressedSplitDotBracketDataFrameList. Since the names
are quite long, the following short cut functions are available for object
DotBracketDataFrame can only contain 5 columns, which are named
The last two columns are optional. The type of the first three has to be
integer, whereas the fourth is a
character and fifth is a
Upon creation and modification, the validity of the contained base pairing information is checked. If the information is not correct, an error is thrown.
