Flatten a nested data.frame

flatten_df(df, factor_ext_to_char = FALSE)

Arguments

df: The data.frame to flatten
factor_ext_to_char: Should extended factor variables be converted to characters (mainly for easy printing)

A flattened data.frame

HDF5 Compounds allow for nesting. Correspondingly, nested data.frames are being produced. This function flattens such a nested data.frame.

For easier printing to the screen, it also allows for coercion of factor_ext to character variables.
