Dear all;
A simple? question.
I'm having a problem with a math expression in the legend of a plot
and I haven't found the way to get this to work, so any help will be
appreciate. Basically I want to include in the plot is the R-squared
and its numerical value, so I tried this:
R2c<-0.82879 # R-squared of calibration model
plot(1:10,1:10)
legend("topleft", legend=c(expression(R[c]^2==format(R2c,nsmall=2))))
Thanks for any hint
PM
