     Given a valid package name as a character string, 'eExplorer'
     collects all the example code from the "R-ex" directory from the R
     library for that package and then displays the names of the code
     examples in a list box. When a name in the list box is clicked,
     the corresponding code will be displayed and users are allowed to
     execute the code or view the help file for the function the
     example code is for.

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

     eExplorer(pkgName, font = "arial 13", getFocus = TRUE)
     getExCode(pkgName)
     getHelpFile(pkgName, fileName)

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

 pkgName: 'pkgName' a character string for the name of an R package of
          interest. The R package needs to be installed

    font: 'font' a character string for the font to be used by the
          widget to display the text. The default is "arial 13"

fileName: 'fileName' a character string for the name of a file in
          "R-ex" with the ".R" extension removed. The file contains a
          chunk of example code and may have a corrsponding help file
          in the "help" directory

getFocus: 'getFocus' a boolean indicating whether a widget should grab
          the focus

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

     'getExCode' and 'getHelpFile' are called by 'eExplorer' to get the
     code examples or help help files contained by a given package.

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

     'eExplorer' does not return anything useful.

_N_o_t_e:
