Set Recipe Roles
Add to or replace the roles of variables in a preprocessing recipe.

recipe |
existing recipe object. |
x, size |
number of counts and trials for the specification of a

stratum |
variable for stratified resampling of cases. |
weight |
numeric variable of case weights for model fitting. |
replace |
logical indicating whether to replace existing roles. |
offset |
numeric variable to be added to a linear predictor, such as in a generalized linear model, with known coefficient 1 rather than an estimated coefficient. |
time, event |
numeric follow up time and 0-1 numeric or logical event
indicator for specification of a |
