     Plot descriptions are templates for creating plots. The variables
     in the plot description are virtual in the sense that they have
     not been resolved to a particular dataset and variable. This
     function performs that mapping, returning a fully self-describing
     plot description from which a real plot can be instantiated
     directly. 

     This function is not typically called by the user, but used
     internally by the 'plotLayout' function.

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

     resolvePlotDescription(desc, .data = 1, .gobi=getDefaultGGobi(), isError = TRUE)

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

    desc: the plot description whose variable references are to be
          resolved.

   .data: the dataset in the ggobi instance relative to which the
          variable references will be resolved. This should be
          specified as a 'ggobiDataset', name or integer.

   .gobi: the ggobi instance in which to find the dataset. If '.data'
          is supplied as a 'ggobiDataset', this is not used. Otherwise,
          it can be a 'ggobi' object or an integer 

 isError: a logical value, if TRUE means an error is generated if  any
          of the variables are not found in the GGobi dataset. The
          purpose of this argument is to allow the caller to turn off
          errors in order to  process multiple plots and then report
          the missing variables for all of them. This is often
          preferrable to reporting the first error and have the user
          solve the problems iteratively.

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

     An object of the same class as the input argument 'desc', but with
     the '.ggobi' and '.data' slots  substituted with the values given
     in the call, and the variable references converted to integers
     identifying the variables within the dataset referenced by this
     object (in the '.data' field).
