reshape_iterations {bayestestR}  R Documentation 
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., iter_1, iter_2, ...
), will return 3 columns
with the \*_index
(the previous index of the row), the \*_group
(the
iteration number) and the \*_value
(the value of said iteration).
