rxCbindStudyIndividual {RxODE} | R Documentation

## Bind the study parameters and individual parameters

### Description

Bind the study parameters and individual parameters

### Usage

    rxCbindStudyIndividual(studyParameters, individualParameters)

### Arguments

`studyParameters` | These are the study parameters, often can be generated by sampling from a population. This can be either a matrix or a data frame
`individualParameters` | A data frame of individual parameters

### Value

Data frame that can be used in RxODE simulations

### Author(s)

### Examples

    # Function for coverting coefficient of covariance into a variance
    lognCv <- function(x){log((x/100)^2+1)}

    set.seed(32)

    nSub  <-  100
    nStud  <-  10

    #define theta
    theta <- c(lka=log(0.5), # log ka
              lCl=log(5), # log Cl
              lV=log(300) # log V
              )

    #define theta Matrix
    thetaMat <- lotri(lCl ~ lognCv(5),
                     lV  ~ lognCv(5),
                     lka ~ lognCv(5))

    nev <- nSub*nStud

    ev1 <- data.frame(COV1=rnorm(nev,50,30),COV2=rnorm(nev,75,10),
                      COV3=sample(c(1.0,2.0),nev,replace=TRUE))

    tmat <-rxRmvn(nStud, theta[dimnames(thetaMat)[[1]]], thetaMat)

    rxCbindStudyIndividual(tmat, ev1)
