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

Arguments

x

`mask', `traps' or `capthist' object

n

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

Details

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