R example using cut()

The following code block shows an example in R:

    clinical.trial<- data.frame(patient = 1:1000,
    age = rnorm(1000, mean = 50, sd = 5),
    year.enroll = sample(paste("19", 80:99, sep = ""),
                                 1000, replace = TRUE))
    
    >clinical.trial<- data.frame(patient = 1:1000,
    +                              age = rnorm(1000, mean = 50, sd = 5),
    +                              year.enroll = sample(paste("19", 80:99, sep = ""),
    +                              1000, replace = TRUE))
    >summary(clinical.trial)
