_D_e_s_c_r_i_p_t_i_o_n:

     This function converts a dataframe of appropriote format to an
     object of class cghRaw.

_U_s_a_g_e:

     make_cghRaw(input)

_A_r_g_u_m_e_n_t_s:

   input: Either a dataframe or character string containing a filename.
          See details for the format.

_D_e_t_a_i_l_s:

     The input should be either a dataframe or a tabseparated textfile
     (textfiles must contain a header). The first four columns should
     contain the name, chromosome and the start and end position in bp
     for each array target respectively. The chromosome and position
     column must contain numbers only. Following these is a column with
     log2 ratios for each of your samples. If the input type is a
     textfile, missing values should be represented as 'NA' or an empty
     field.

_V_a_l_u_e:

     This function returns an object of class 'cghRaw-class'.
