Set Transformations in Baseline Objects
Description
Set Transformations in Baseline Objects
Usage
## S4 method for signature 'BaselineObject'
set_transformations(object, ..., overwrite = FALSE)
Arguments
object |
|
... |
named transformation functions. See details for more information. |
overwrite |
If |
Details
Transformation functions are evaluated in order and create or overwrite a column in the data.frame with that
name. The function should have signature function(data)
, taking a data.frame
(specifically a
BaselineDataFrame
object from generate(BaselineObject)
) and return a vector with length identical to the total
number of patients. The @BaselineObject
slot of the BaselineDataFrame may be accessed directly or with
get_quantiles()
to create transformations. See binary_cutoff()
.
Value
An updated BaselineObject
Examples
baseline <- create_baseline_object(
100, 50, 100,
covariates = baseline_covariates(
names = "age", means_int = 55,
covariance_int = covariance_matrix(5)
)
)
set_transformations(baseline, age_scaled = function(data) scale(data$age))
