Hello all,
I am an R novice and I have a simple question and hope somebody can help me out.
I need to place several labels in a plot, this labels are some kind of text and also some objects (which come from some more complicated R calculations).
In one of this labels I'd like to place a superscript, however I cannot find a way to place both the expression and the object in the same label.
Thanks in advance and best regards.
Please look at the example below:
# my objects eonr <- 75 yldeonr <- 150 r_2 <- 0.95
# the plot and simple labels
plot(0:100, 0:100)
text(60,40, paste("EONR=",eonr))
text(60,36, paste("Yield at EONR=",yldeonr))# I'd like to place the superscript on the r
text(60,32, paste("Pseudo r^2=",r_2))# This does not seem to work ... I can get the subscript # but now I cannot paste the r_2 object. Any ideas ?
text(60,28, expression(paste("Pseudo r" ^2, "=" r_2)))-- Jose A. Hernandez Department of Soil, Water, and Climate University of Minnesota 1991 Upper Buford Circle St. Paul, MN 55108
