Grouping of patients by scores.

Description

Addition of a new attribute that categorizes patients in specified groups to an ABT class object.

groupAttribABT(objName = "inData", sourceAttrib = "Age", 
    newAttribName = "AgeGroup", groupNames = c("young", "middle", "elderly"),
    groupLimmits = list(c(0, 39), c(40, 64), c(65, 200)))

Arguments

objName

a character specifying the name of an ABT class object produced by readABT.

sourceAttrib

a character specifying the name of source attribute. The contents of this attribute must be integer of numeric.

newAttribName

a character specifying the name of the new attribute.

groupNames

a character vector specifying the names of categories.

Value

an ABT class object

Examples

inData <- readABT(fileName = system.file("extdata","toy.xlsx",package="AntibodyTiters"))
inDataA <- groupAttribABT(objName = "inData", sourceAttrib = "Age", 
    newAttribName = "AgeGroup", groupNames = c("young", "middle", "elderly"),
    groupLimmits = list(c(0, 39), c(40, 64), c(65, 200)))
plotAllABT("inDataA", lineAttrib = "AgeGroup", addPoints = TRUE, savePDF = FALSE, 
    orderOfCategories = c("young", "middle", "elderly"), type = "weeks")
plotAllABT("inDataA", lineAttrib = "AgeGroup", addPoints = TRUE, savePDF = FALSE, 
    orderOfCategories = c("young", "middle", "elderly"), type = "M1", geometricMean = TRUE)
