[R] ggplot 'annotate problem' again.

Mon Mar 1 08:16:58 CET 2010

Hi,

I suggest to use geom_text to add multiple labels. 
Put all the information needed by for your labels in a dataframe:

lab = data.frame(x=namposts+2.5, y = temprange[2], label= mlabs)

and add them to the plot:

p + geom_text(data=lab,aes(x,y,label=label), size=2.5,colour='black',
    hjust = 0, vjust = 0)

regards,
 Stefan
