Create a derivation_slice Object

Create a derivation_slice object as input for slice_derivation().

Usage

derivation_slice(filter, args = NULL)

Arguments

filter

An unquoted condition for defining the observations of the slice

Comparing derived numeric variables to fixed values, e.g., PCHG <= -90, may give unexpected results due to floating point representation. For details and solutions see the "Floating Point Comparisons" section in vignette("concepts_conventions").

Default value

none

args

Arguments of the derivation to be used for the slice

A params() object is expected.

Default value

NULL

Value

An object of class derivation_slice
