No, because all of the elements of a matrix must be of the same mode,
but a dataframe is a data structure that can have heterogeneous
columns. It's unclear from your question where the "table" is
located
-- in a file perhaps? If so, you can use read.table() to read the data
into a dataframe.
I hope this helps,
John
