Utility function to use to set the control arguments of cca
ccacontrol(
algorithm = "quick",
full = FALSE,
itercca = 1,

np = 15,
gl = 100,
ff = 0.4,
cr = 0.9,
proc = FALSE,
ps = FALSE
)
The algorithm used to compute the median ranking. One among"BB", "quick" (default), "fast" and "decor"
Specifies if the median ranking must be searched in the universe of rankings including all the possible ties. Default: FALSE
Number of iterations of cca
Number of iterations for "fast" and "decor" algorithms. itermax=10 is the default option.
(for "decor" only) the number of population individuals. np=15 is the default option.
(for"decor" only) generations limit, maximum number of consecutive generations without improvement. gl=100 is the default option.
(for"decor" only) the scaling rate for mutation. Must be in [0,1]. ff=0.4 is the default option.
(for"decor" only) the crossover range. Must be in [0,1]. cr=0.9 is the default option.
(for "BB" only) proc=TRUE allows the branch and bound algorithm to work in difficult cases, i.e. when the number of objects is larger than 15 or 25. proc=FALSE is the default option
If PS=TRUE, on the screen some information about how many branches are processed are displayed. Default value: FALSE
