a single integer. If positive, size for the resulting object: number of elements for a vector (including lists), rows for a matrix or data frame or lines for a function. If negative, all but the n last/first number of elements of x.

other arguments passed to subset

Value

An object of the same class as x, but (usually) fewer rows.

Details

These custom S3 methods retain the class of the target object, unlike the default methods applied to `mask', `Dsurface', `traps' or `capthist' objects.
