restore: Restore S3 class properties.

In hadley/ggstat: Statistical Computations for Visualisation

Description

When an S3 class is built on top of an atomic vector, it's often resonable compute directly on those underlying values. This generic allows you to restore important attributes from the original vector to the new vector, so that it continues to behave as expected.

Usage

restore(old, new)

Arguments

old	Old S3 vector
new	New S3 vector. Should be same typeof() as old.

Examples

restore(Sys.Date(), 1)
restore(Sys.time(), 1)

dt <- difftime(Sys.time(), Sys.time() - 100)
restore(dt, 10)
