I would like to be able to do something like this: <<echo=F,fig=T,width=mywidth>>= ... @ with mywidth set in a previous code chunk. Is there a way to do this in Sweave?
Not in the <<>>, but you could set a hook for fig:
From Sweave docs:
If option "SweaveHooks" is defined as list(fig = foo), and foo is a function, then it would be executed before the code in each figure chunk. This is especially useful to set defaults for the graphical parameters in a series of figure chunks.
Thanks. I guess what I really want to do is switch between one of two settings. Only one value can be in the defaults, and I would like some way of setting the other value. This might not be easily possible, but I thought I would ask.
