sgCMatrix-class: Class "sgCMatrix" -- Sparse Ordered Lists of Symbols
Description
Sparse pseudo matrices in column-compressed form for storing ordered
lists of symbols.
Arguments
Objects from the Class
Most frequently, an object is created upon creation of an object of
class '>sequences or
'>sequencerules.
Objects can also be created by calls of the form
new("sgCMatrix", ...).
Slots
p:
an integer vector of length the number of columns
in the matrix plus one. These are zero-based pointers into
i, i.e. to the first element of a list. However, note that
the last element contains the number of elements of i.
i:
an integer vector of length the number of non-zero
elements in the matrix. These are zero-based symbol
indexes, i.e. pointers into the row names if such exist.
Dim:
an integer vector representing the number of symbols
and the number of lists.
Dimnames:
a list with components for symbol and
list labels.
factors:
unused, for compatibility with package
Matrix only.
