Count Binary Patterns
Every row of the binary matrix x is transformed into a binary
pattern and these patterns are counted.
countpattern(x, matching=FALSE)
x |
A matrix of binary observations |
matching |
If TRUE an additional vector is returned which stores which row belongs to which pattern |
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
