setdiff {prob} | R Documentation |
Calculates the (nonsymmetric) set difference of subsets of a probability space.
setdiff(x, ...) ## Default S3 method: setdiff(x, y, ...) ## S3 method for class 'data.frame': setdiff(x, y, ...) ## S3 method for class 'ps': setdiff(x, y, ...)
x, y |
vectors, data frames, or ps objects containing a sequence of items (conceptually). |
... |
further arguments to be passed to or from other methods. |
This function operates row-wise on dataframes, and element-wise among the outcomes of ps
objects. The elements of setdiff(x,y)
are those elements in x
but not in y
. The definition is taken to match the version in the base
package.
A data frame or subset of a probability space of the same type as its arguments.
