How Can I add a Textbox to a plot created with ggplot2?

How Can i add a Textbox to a plot created with ggplot2?

I want to create a Plot that has a second Legend like box in which i
can write free text.

I want to use that box to plot some numbers like median mean etc.

Cheers,

Michael

Hi Michael,

You can use geom_text to add text positioned in data units, or
grid.text to add text positioned in absolute units.

Thanks a lot for the answer.
Is there an easy way to add a box around that text?
And is there a way to make parts of the text look bold?

Not with geom_text, but you have total control if you use grid.
There's a good example in the R graphics book.

You could also try this,

library(ggExtra)
# and version 0.6.5 of gridExtra

p = qplot(1:2, 1:2) + theme_bw()

d <- data.frame(my.values = c( "x=12", "y=1.34"))

p + annotate("table", x=1.2, y=1.5, table=d, just=c("left", "top"),
theme=theme.list(show.box = TRUE, separator = "black",
show.csep = TRUE, show.rsep = TRUE, show.colnames=T))

HTH,

How do I download gridExtra 0.6.5 from trunk?
It appears that the latest version is 0.6.1 in R-forge

I was able to download it to my desktop from here:
 
http://code.google.com/p/gridextra/updates/list

but after I decompress the file and replace it in my library, it
still says that the version is 0.6.1 (sessionInfo()) and the new function
to apply the argument just=c("left","top") doesn't work

The source package is at googlecode, you can get it with svn or in the
download list. You seem to have installed it incorrectly, somehow.

The code will also get transferred to r-forge by tomorrow, and if it
passes the checks there (as it should) I'll update the CRAN version
too.
