Source: R/Transform_Rate.R
Transform_Rate.Rd

[Stable]

Convert from input data format to needed input format to derive KRI for an Assessment. Calculate a site-level rate.

Usage

Transform_Rate(
  dfInput,
  strNumeratorCol = "Numerator",
  strDenominatorCol = "Denominator"
)

Arguments

dfInput

data.frame Input data with one record per subject. Created by passing Raw+ data into Input_Rate(). Expected columns: GroupID, GroupLevel, Numerator, Denominator and/or columns specified in strCountCol and strGroupCol.

strNumeratorCol

string Column to be counted. Defaults to "Numerator".

strDenominatorCol

string Column name for the numerical Exposure column. Defaults to "Denominator".

Value

data.frame with one row per site with columns GroupID, GroupLevel, Numerator, Denominator, and Metric.

Details

This function transforms data to prepare it for the analysis step. It is currently only sourced for the Adverse Event, Disposition, Labs, and Protocol Deviations Assessments.

Data Specification

(dfInput) must include the columns specified by strNumeratorCol and strDenominatorCol. Required columns include:

  • GroupID - Group ID

  • GroupLevel - Group Type

  • Numerator - Number of events of interest; the actual name of this column is specified by the parameter strNumeratorCol

  • Denominator - Number of days on treatment; the actual name of this column is specified by the parameter strDenominatorCol

Examples

dfTransformed <- Transform_Rate(
  analyticsInput,
  strNumeratorCol = "Numerator",
  strDenominatorCol = "Denominator"
)
