Well, yes, I suppose there is that. I've mentally (perhaps
inappropriately) lumped substitute() with parse() as being subject to
fortune(106) and have avoided it.
And this is also why I have learned to say "I don't know of..." rather
than "There is not..." :)

Hi all,
Is there any way for me to to string in the argument of
qplot or ggplot? for
example
qplot(x='carat',y='price',data=diamonds,geom=c('point','smooth'))
instead of
qplot(x=carat,y=price,data=diamonds,geom=c('point','smooth'))
I don't know of a way using qplot, but it is possible with
ggplot. Use
aes_string instead of aes:
ggplot(diamonds, aes(x=carat, y=price)) + geom_point() + geom_smooth()
ggplot(diamonds, aes_string(x="carat", y="price")) + geom_point() +
geom_smooth()
Thanks!!
