## S4 method for signature 'data.frame,formula'
mutate_random(data, input, ...)

## S4 method for signature 'data.frame,character'
mutate_random(data, input, envir = parent.frame(), ...)

## S4 method for signature 'data.frame,list'
mutate_random(data, input, ...)

## S4 method for signature 'data.frame,covset'
mutate_random(data, input, ...)

## S4 method for signature 'data.frame,covobj'

Arguments

data	the data.frame to mutate.
input	an unquoted R formula; see details.
...	additional inputs.
envir	environment for object lookup.

Examples

data <- data.frame(ID=1:10, GROUP = sample(c(1,2,3),10,replace=TRUE))

mutate_random(data, AGE[40,90] ~ rnorm(55,50))
mutate_random(data, RE ~ rbeta(1,1) | GROUP)

e <- list(lower=40,upper=140,mu=100,sd=100)

egfr <- covset(EGFR[lower,upper] ~ rnorm(mu,sd))

mutate_random(data,egfr,envir=e)
