Re: a stupid doubt using geom_text...

[Ista Zahn]

I think you are looking for ?annotate

Hi Izanh!

Thanks a lot!

I've tried, changing the yellow line by: + annotate("text", x=1.2,y=1, label = caption, angle =90)   

but I got the same result...

I attached my data just in case it would be easier to take a look...

You need to put the + on the previous line
