| or.globalSeg {GeneR} | R Documentation |
This function compute union of two objects of class globalSeg a and b.
When used with only one parameter, or(A) returns the union of A.
or.globalSeg(a, b = NULL, byrows = FALSE,...)
a,b |
elements of class globalSeg |
byrows |
if TRUE, a and b must be lists of same
length, and intersection is computed for each elements from a
with its homologue in b.
