_D_e_s_c_r_i_p_t_i_o_n:

     A driver for 'Sweave' that translates R code chunks in LaTeX
     files.

_U_s_a_g_e:

     RweaveLatex()

     RweaveLatexSetup(file, syntax, output = NULL, quiet = FALSE,
                      debug = FALSE, echo = TRUE, eval = TRUE,
                      keep.source = FALSE, split = FALSE,
                      stylepath, pdf = TRUE, eps = TRUE)

_A_r_g_u_m_e_n_t_s:

    file: Name of Sweave source file.

  syntax: An object of class 'SweaveSyntax'.

  output: Name of output file, default is to remove extension '.nw',
          '.Rnw' or '.Snw' and to add extension '.tex'. Any  directory
          names in 'file' are also removed such that the output is
          created in the current working directory.

   quiet: If 'TRUE' all progress messages are suppressed.

   debug: If 'TRUE', input and output of all code chunks is copied to
          the console.

stylepath: See 'Details'.

    echo: set default for option 'echo', see details below.

    eval: set default for option 'eval', see details below.

keep.source: set default for option 'keep.source', see details below.

   split: set default for option 'split', see details below.

     pdf: set default for option 'pdf', see details below.

     eps: set default for option 'eps', see details below.

_D_e_t_a_i_l_s:

     The LaTeX file generated needs to contain '\usepackage{Sweave}',
     and if this is not present in the Sweave source file, it is
     inserted by the 'RweaveLatex' driver. If 'stylepath = TRUE', a
     hard-coded path to the file 'Sweave.sty' in the R installation is
     set in place of 'Sweave'. The hard-coded path makes the TeX file
     less portable, but avoids the problem of installing the current
     version of 'Sweave.sty' to some place in your TeX input path. 
     However, TeX may not be able to process the hard-coded path if it
     contains spaces (as it often will under Windows) or TeX special
     characters.

     The default in R prior to 2.7.0 was 'stylepath = TRUE'.  It is now
     taken from the environment variable 'SWEAVE_STYLEPATH_DEFAULT', or
     is 'FALSE' it that is unset or empty.  If set, it should be
     exactly 'TRUE' or 'FALSE': any other values are taken as 'FALSE'.

_S_u_p_p_o_r_t_e_d _O_p_t_i_o_n_s:

     'RweaveLatex' supports the following options for code chunks (the
     values in parentheses show the default values):

     _e_c_h_o: logical ('TRUE'). Include S code in the output file?

     _k_e_e_p._s_o_u_r_c_e: logical ('FALSE').  When echoing, if 'keep.source ==
          TRUE' the original source is copied to the file. Otherwise,
          deparsed source is echoed.

     _e_v_a_l: logical ('TRUE'). If 'FALSE', the code chunk is not
          evaluated, and hence no text or graphical output produced.

     _r_e_s_u_l_t_s: character string ('verbatim'). If 'verbatim', the output
          of S commands is included in the verbatim-like Soutput
          environment. If 'tex', the output is taken to be already
          proper latex markup and included as is. If 'hide' then all
          output is completely suppressed (but the code executed during
          the weave).

     _p_r_i_n_t: logical ('FALSE') If 'TRUE', each expression in the code
          chunk is wrapped into a 'print()' statement before
          evaluation, such that the values of all expressions become
          visible.

     _t_e_r_m: logical ('TRUE'). If 'TRUE', visibility of values emulates
          an interactive R session: values of assignments are not
          printed, values of single objects are printed. If 'FALSE',
          output comes only from explicit 'print' or 'cat' statements.

     _s_p_l_i_t: logical ('FALSE'). If 'TRUE', text output is written to
          separate files  for each code chunk.

     _s_t_r_i_p._w_h_i_t_e: character string ('false'). If 'true', blank lines at
          the beginning and end of output are removed. If 'all', then
          all blank lines are removed from the output.

     _p_r_e_f_i_x: logical ('TRUE'). If 'TRUE' generated filenames of figures
          and output have a common prefix.

     _p_r_e_f_i_x._s_t_r_i_n_g: a character string, default is the name of the
          '.Snw' source file.

     _i_n_c_l_u_d_e: logical ('TRUE'), indicating whether input statements for
          text output and includegraphics statements for figures should
          be auto-generated. Use 'include = FALSE' if the output should
          appear in a different place than the code chunk (by placing
          the input line manually).

     _f_i_g: logical ('FALSE'), indicating whether the code chunk produces
           graphical output. Note that only one figure per code chunk
          can be processed this way.

     _e_p_s: logical ('TRUE'), indicating whether EPS figures should be
          generated. Ignored if 'fig = FALSE'. 

     _p_d_f: logical ('TRUE'), indicating whether PDF figures should be
          generated. Ignored if 'fig = FALSE'.

     _p_d_f._v_e_r_s_i_o_n, _p_d_f._e_n_c_o_d_i_n_g: passed to 'pdf' to set the version and
          encoding.  Defaults taken fron 'pdf.options()'.

     _w_i_d_t_h: numeric (6), width of figures in inches.

     _h_e_i_g_h_t: numeric (6), height of figures in inches.

     _e_x_p_a_n_d: logical ('TRUE').  Expand references to other chunks so
          that only R code appears in the output file.  If 'FALSE', the
          chunk reference (e.g. '<<chunkname>>') will appear.  The 
          'expand=FALSE' option requires 'keep.source = TRUE' or it 
          will have no effect.

     _c_o_n_c_o_r_d_a_n_c_e: logical ('FALSE').  Write a concordance file to link
          the input line numbers to the output line numbers.  This is
          an experimental feature; see the source code for the output
          format, which is subject to change in future releases.
