Grouped data from multiple vectors
Combines two or more vectors, possibly of different lengths, producing a data frame with a second column indicating which of these vectors that row came from. This is mostly useful for getting data into a form suitable for use in high level Lattice functions.
one or more vectors of the same type (coercion is attempted if not), or one or more data frames with similar columns, with possibly differing number of rows.
When all the input arguments are vectors, a data frame with two columns
all the vectors supplied, concatenated
factor indicating which vector the corresponding
When all the input arguments are data frames, the result of
rbind applied to them, along with an additional
which column as described above.
