Calculates the intersection of subsets of a probability space. Comparisons are made row-wise, so that in the data frame case, intersect(A,B) is a data frame with those rows that are both in A and in B.
intersect(x, …)# S3 method for default
intersect(x, y, …)
# S3 method for data.frame
intersect(x, y, …)
# S3 method for ps
intersect(x, y, …)
vectors, data frames, or ps objects containing a sequence of elements (conceptually).
further arguments to be passed to or from other methods.
A vector, data frame, or subset of a probability space of the same type as its arguments.
This is a generic function, extended from the intersect function in the base package. The elements of intersect(x,y) are those elements in x and in y. The original definition is preserved in the case that x and y are vectors of the same mode.
