initMC {multicool} | R Documentation |
This function initialises the permutation object. It must be called
before nextPerm
can be called
initMC(x)
x |
a vector of integers, reals, logicals or characters |
a object of class mc
which is a list containing elements
mode - the mode of the original data in x
, "integer",
"double", or mode(x)
set - either the multiset being permuted if mode
is
"integer" or a set of integers corresponding to the elements of
the multiset
elements - if mode
is not "integer" then this contains
the elements being permuted otherwise NULL
length - the length of the multiset
mc - a pointer to the internal C++ Multicool object. Users should not use this unless they really know what they are doing

x = c(1,1,2,2) m1 = initMC(x) m1 ## a non-integer example x = rep(letters[1:4],c(2,1,2,2)) m2 = initMC(x) m2
