is_mgcv_smooth {gratia}

Check if objects are smooths or are a particular type of smooth

Description

Check if objects are smooths or are a particular type of smooth

Usage

is_mgcv_smooth(smooth)

stop_if_not_mgcv_smooth(smooth)

check_is_mgcv_smooth(smooth)

is_mrf_smooth(smooth)

Arguments

smooth

an R object, typically a list

Details

Check if a smooth inherits from class "mgcv.smooth". stop_if_not_mgcv_smooth() is a wrapper around is_mgcv_smooth(), useful when programming for checking if the supplied object is one of mgcv's smooths, and throwing a consistent error if not. check_is_mgcv_smooth() is similar to stop_if_not_mgcv_smooth() but returns the result of is_mgcv_smooth() invisibly.
