MapIds: Map covariate and row Ids so they start from 1

Description

this functions takes covariate data and a cohort/population and remaps the covariate and row ids, restricts to pop and saves/creates mapping

Usage

MapIds(covariateData, cohort = NULL, mapping = NULL)

Value

a new covariateData object with remapped covariate and row ids

Arguments

covariateData

a covariateData object

cohort

if specified rowIds restricted to the ones in cohort

mapping

A pre defined mapping to use

Examples

covariateData <- Andromeda::andromeda(
  covariates = data.frame(rowId = c(1, 3, 5, 7, 9), 
                          covariateId = c(10, 20, 10, 10, 20),
                          covariateValue = c(1, 1, 1, 1, 1)),
  covariateRef = data.frame(covariateId = c(10, 20), 
                              covariateNames = c("covariateA", 
                                                 "covariateB"),
                              analysisId = c(1, 1)))
mappedData <- MapIds(covariateData)
# columnId and rowId are now starting from 1 and are consecutive
mappedData$covariates
