Usage

binary_cutoff(name, int_cutoff, ext_cutoff)

Arguments

name

variable to transform

int_cutoff

cut-off for internal patients, numeric between 0 and 1

ext_cutoff

cut-off for external patients, numeric between 0 and 1

Value

Examples

# Creates a simple function, where `data` is a `BaselineDataFrame`:
function(data) {
  ext <- data$ext == 0
  q <- get_quantiles(data, name)
  ifelse(ext, q > int_cutoff, q > ext_cutoff)
}
#> function (data) 
#> {
#>     ext <- data$ext == 0
#>     q <- get_quantiles(data, name)
#>     ifelse(ext, q > int_cutoff, q > ext_cutoff)
#> }
