Process set_values_to Argument

Description

Usage

process_set_values_to(dataset, set_values_to = NULL, expected_types = NULL)

Arguments

dataset

Input dataset

set_values_to

Variables to set

A named list returned by exprs() defining the variables to be set, e.g. exprs(PARAMCD = "OS", PARAM = "Overall Survival") is expected. The values must be symbols, character strings, numeric values, expressions, or NA.

If the argument is specified, the specified variables are checked whether the specified type matches the type of the variables created by set_values_to.

Value

The input dataset with the variables specified by set_values_to added/updated

Examples

library(dplyr)
data <- tribble(
  ~AVAL,
  20
)

try(
  process_set_values_to(
    data,
    set_values_to = exprs(
      PARAMCD = BMI
    )
  )
)

try(
  process_set_values_to(
    data,
    set_values_to = exprs(
      PARAMCD = 42
    ),
    expected_types = c(PARAMCD = "character")
  )
)
