Hi,
I have a list of lists that I would like to convert into a dataframe
such
that the name(?) of the individual lists is replicated as rows with
each
item in the list listed in another column.
I have provided a partial from my list: (let's say the list is called
"help.me")
Actually only a list of numeric vectors:
new.df <- stack(as.data.frame(help.me))
