R help - Nov 2014 - Adapt sweave function to produce an automatic pdf.

Hi All,

I want to make a climate method ("sweave_function"). The aim is to be
able
to adapt sweave code that produces an automatic pdf so that it can works
for my climate object. i.e. instead of compile pdf, I call :
data_obj$sweave_function() and get the pdf. for instance I have
boxplot_method() and I want to output it in this way. Thanks for the help!!!

Ex: This how I started but I don't understand how I can proceed.

climate$methods(sweave_function = function(climate_data_objs_str,
climate_data_objs_ind
) {

#---------------------------------------------------------------------------------------------
  #  This function returns the pdf using sweave function in R
  #  The required arguments are:
  #   climate_data_objs_str  : list of the names of climate data objects in
the climate object
  #   climate_data_objs_ind  : list of the indices of climate data object
in the climate object
  #   note that one of the above arguments is enough.

#--------------------------------------------------------------------------------------------


  # get_climate_data_objects returns a list of the climate_data objects
specified
  # in the arguements.
  # If no objects specified then all climate_data objects will be taken by
default

  climate_data_objs = get_climate_data_objects(climate_data_objs_str,
climate_data_objs_ind)
})

You need to either dynamically generate the entire final .tex file including the
preamble and so forth via your function(s)

or:

alternatively use a .Rnw Sweave "master" file template that contains
the static content and then in that file, insert the dynamic content using one
or more directives along the lines of \input{InsertContentHere.tex}, where
InsertContentHere.tex contains raw TeX content to be inserted at that point in
the master file when processed by Sweave.

The content of the *.tex files can be generated via various R functions
including ?cat for raw text and others like the xtable() function in the CRAN
package of the same name or the latex() function in Hmisc, which can be used to
create tables, etc.

Note that the content of InsertContentHere.tex will not itself be processed by
Sweave, as if it was a "child" .Rnw file. If you want that type of
functionality, you would need to use \SweaveInput{InsertContentHere.Rnw}.

Once you have your final .tex file, you can then run pdflatex on that file via
?system.
