intersect {prob} | R Documentation |
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, ...) ## Default S3 method: intersect(x, y, ...) ## S3 method for class 'data.frame': intersect(x, y, ...) ## S3 method for class 'ps': intersect(x, y, ...)
x, y |
vectors, data frames, or ps objects containing a sequence of elements (conceptually). |
... |
further arguments to be passed to or from other methods. |
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.
A vector, data frame, or subset of a probability space of the same type as its arguments.
