Takes any combination of several data frames or matrices and creates a new data
frame. The rows are defined by a union of all row names in the arguments,
and the columns are defined by a union of all column names in the arguments. The data
are loaded into this new frame where column and row names match the individual
inputs. Duplicates are tolerated with the last one specified being the one
kept. NAs are returned for combinations of rows and columns where no data
exist. Factors are processed as necessary.

a list of data frames, matrices, or any combination.
