Fills up a vector
This function replaces all the empty characters "" and/or
NAs with the value of the closest preceding the preceding
non-NA/"" element. The function is used to populate
dataframe or matrice columns where only the cells of the first row in
a set of partially identical rows are explicitly populated and the
following are empty.
