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

     A collection and description of functions for  the usage of
     Rmetrics under SPlus. 

     The functions are in alphabetical order:

       '%x%'            Computes generalised kronecker product of two arrays,
       'as.Date'        Converts date represenatation,
       'cov'            Computes covariance of vectors,
       'data'           Loads or lists specified data sets,
       'download.file'  Downloads files from Internet using "lynx" or "wget",
       'embed'          Embeds time series into a low-dimensional space,
       'forwardsolve'   Solves linear equations for lower triangular systems,
       'match.fun'      Verifies function from a 'function argument',
       'model.weights'  Returns weights of a model frame,
       'nlm'            Wraps R's "nlm" on S's "nlminb" optimizer,
       'NCOL'           Returns number of columns in a vector, array or data frame,
       'NROW'           Returns number of rows in a vector, array or data frame,
       'optim'          Wraps R's "optim" on S's "nlminb" optimizer,
       'sd'             Computes the standard deviation,
       'strsplit'       Splits elements of a character vector into substrings,
       'which.max'      Determines index of the maximum of a numeric vector,
       'which.min'      Determines index of the minimum of a numeric vector.

_N_o_t_e:

     These functions are only used when running Rmetrics under SPlus.
     Note, that only the functionality is  supported which is required
     running these R functions for Rmetrics under Splus.

_A_u_t_h_o_r(_s):

     Diethelm Wuertz for the Rmetrics R-port.
