Write an index file for the current R2html output.
createIndxFile(HTMLfile,navfile,listfile,title="R listing")
The file name for the HTML files.
The name for the HTML navigation frame file.
The name for the HTML listing file.
The title for the listing.
nil
createIndxFile opens a new HTML index file. If there is another file with the same name, it will be overwritten. This is intentional, as the user may want to run R2html repeatedly without generating multiple sets of files. It then writes the frameset definition into the file and closes it.
