to display the help (here, of plot) directly to the screen. So we could use something like: <<echo=TRUE,print=FALSE,eval=FALSE>>= ?plot @ <<echo=FALSE,print=TRUE,eval=TRUE>>= cat(readLines(as.character(?plot)),sep="\n") @ But this doesn't work (latex compilation error) as weird characters appear in the produced tex, at some places (tabulations?), like: _T_h_e _D_e_f_a_ (not sure what it will look like in this email, but emacs reads things like _^HT_^HH_^He...). Maybe an encoding problem? I tried specifying different encoding to readLines, with no luck (latin1, UTF-8). Otherwise, the help appears in the .tex.
