Hi everyone.
I have a linear regression where I retrieve the R2 like this:
r2 = sprintf('%4.2f %s',(summary(reg1)$r.squared))
In my figure I have a legend where I would like to add that R2 value to the
legend text.
Something like: My text R^2 = r2
legend('topright', inset = .05, title='light ratios', pch = c(21),
c(paste('Green/Red', R^2, '=', r2)), horiz=F,pt.bg =c('gray', 'black'), cex
= 0.75, bg = 'white')
legend('topright', inset = .05, title = 'light ratios', pch = 21,
legend = substitute('Green/Red' ~~ R^2 == r2, list(r2=r2)),
horiz = FALSE, pt.bg = c('gray', 'black'), cex = 0.75,
bg = 'white')

But its not working.
Any help would be appreciated.
Regards,
Phil
