countpattern {e1071} | R Documentation |
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
of x in pat . |
