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
