Hi Jessica,
x <- call("plot", quote(pcaI))
eval(x)
that said, I suspect you would be better off avoiding this idiom
altogether. Storing unevaluated calls is akin to putting tomatoes on
your sandwich before packing it for work---you can do it but you end
up with a soggy sandwich by the time you are eating it. Better to
store the bread and tomatoe separately and put them together when you
want a delicious sandwich.
Cheers,
Josh
