eval() not working with ggplot, returns “non-numeric argument to binary operator”

I have the following ggplot element stored as text:
eval(parse(text = " annotate('text', as.Date('2013-12-31'), 30.31049879 * 1.02,
label = paste0( 19.48 , percent( 0.055 )), color = 'Blue') +
annotate('text', as.Date('2013-12-31'), 33.341548669 * 1.02,
label = paste0( 21.43 , percent( 0.048 )), color = 'Blue') "))
eval() returns error "non-numeric argument to binary operator" since it's trying to add the two parts together, but the plus sign is used differently with ggplot. Is there any way to dodge this problem?

What are you using theparsefunction for? Since you are hard coding everything, would it not be easier to just have theannotate()simply.

@Jrakru56 I have about twenty of those annotations so I figured out it might be easier to add them using a loop instead of hardcoding twenty rows.

if that's the case, then you might be better off creating adata.frameorlistto hold yourx,yand 'label

Soemthing like this:dt<- mtcars; ggplot(data=dt) + geom_point(aes(x=mpg, y =hp )) + geom_text(aes(label = rownames(dt), x =mpg, y = hp))

This was solved by putting ggplot() + at the start of the code, i.e.
eval(parse(text = "ggplot() +
annotate('text', as.Date('2013-12-31'), 30.31049879 * 1.02,
label = paste0( 19.48 , percent( 0.055 )), color = 'Blue') +
annotate('text', as.Date('2013-12-31'), 33.341548669 * 1.02,
label = paste0( 21.43 , percent( 0.048 )), color = 'Blue') "))
