Calculates the (nonsymmetric) set difference of subsets of a probability space.

`setdiff(x, …)`# S3 method for default
setdiff(x, y, …)

# S3 method for data.frame
setdiff(x, y, …)

# S3 method for 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.

A data frame or subset of a probability space of the same type as its arguments.

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.

# NOT RUN { S <- cards() A <- subset(S, suit == "Heart") B <- subset(S, rank == "A" ) setdiff(B, A) # }
