I would like to take this: .img(plot(1:10), filename="a")
and produce plot(1:10) ie. whenever .img is used, I want to take the first argument and throw away everything else. (I am trying to produce a Sweave like environment in which I can apply certain functions, but not have them displayed in the output) I think I should be able to do it using substitute, but I don't know how to operate on language objects. Any hints would be appreciated. Thanks, Hadley ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
