Using this data as an example
dat <- read.table(textConnection("Id myvar
12 1
12 2
12 6
34 9
34 4
34 8
65 15
65 23"), header = TRUE)
closeAllConnections()
how can I create another data set that does not have duplicate entries
for 'Id', but the included values
are randomly selected from the available ones.
Thanks!
Juliet
