\title{Reshape estimations with multiple iterations (draws) to long format}
\usage{
reshape_iterations(x, prefix = c("draw", "iter", "iteration", "sim"))

reshape_draws(x, prefix = c("draw", "iter", "iteration", "sim"))
}
\arguments{
\item{x}{A data.frame containing posterior draws obtained from \code{estimate_response} or \code{estimate_link}.}

\item{prefix}{The prefix of the draws (for instance, \code{"iter_"} for columns named as \verb{iter_1, iter_2, iter_3}). If more than one are provided, will search for the first one that matches.}
}
\value{
Data frame of reshaped draws in long format.
}
\description{
Reshape a wide data.frame of iterations (such as posterior draws or bootsrapped samples) as columns to long format. Instead of having all iterations as columns (e.g., \verb{iter_1, iter_2, ...}), will return 3 columns with the \verb{\\*_index} (the previous index of the row), the \verb{\\*_group} (the iteration number) and the \verb{\\*_value} (the value of said iteration).
