: Re: [R] Manipulation of data.frame into an array
This is one of those instances where a less superficial knowledge of R's
technical details comes in really handy.
What you need to do is convert the data frame to a single (numeric) vector for,
e.g. a matrix() call. This can be easily done by

Hello,
I am not sure I understand the question, but see if the following is
what you want.
split(Imputed, cumsum(c(0, diff(Imputed$Y) != 1)))
