- _A_r_g_u_m_e_n_t_s:
-
- ... : these arguments are of either the form value
- or tag=value. Component names are created
- based on the tag (if present) or the deparsed
- argument itself.
-
- row.names : a character vector giving the row names for
- the data frame.
-
- col.names : a character vector giving names for the vari-
- ables in the data frame.
-
- as.is : a logical value indicating whether character
- variables should be left ``as is'' or con-
- verted to factors.
-
- _V_a_l_u_e:
-
- A data frame. Data frames are the fundamental data
- structure used by most of R's modeling software. They
- are tightly coupled collections of variables which
- share many of the properties of matrices. The main
- difference being that the columns of a data frame may
- be of differing types (numeric, factor and character).
-
- as.data.frame attempts to coerce its argument to be a
- data frame.
-
- is.data.frame returns TRUE if its argument is a data
- frame and FALSE otherwise.

- _S_e_e _A_l_s_o:
