So I have a column like this
stimulus
005_y_f_n_b_m
004_m_m_n_b_m
005_y_f_s_b_m
And I want to create a new column like this:
baseFace
005
004
005
How do I extract one small peace of information from the existing column to a new column? My goal is to split the stimulus column into several columns (spreading out all the information from the column like y, f, n etc since they all have a specific meaning).
Any help is hugely appreciated.
