Keywords
multivariate
Usage
countpattern(x, matching=FALSE)
Arguments
x

A matrix of binary observations

matching

If TRUE an additional vector is returned which stores which row belongs to which pattern

Value

A vector of length 2\^ncol(x) giving the number of times each pattern occurs in the rows of x. The names of this vector are the binary patterns. They are sorted according to their numeric value. If matching is TRUE, a list of the following two vectors is returned.

pat

Numbers of patterns as described above.

matching

Vector giving the position of the pattern of each row of x in pat.
