Dear all,
W2k, R2.4.0
I want to place a legend in a regression plot, stating the adjusted
R-square value. After some struggle with the coding I am nearly there, but
only nearly. The best try so far is:
legend("topleft", expression(paste(R[adj]^2), " = 0.66"))
This places the proper information in the legend, but I get a linebreak
before the "= 0.66" and I want the expression on one single line. All
adjustments from this code I have tried so far either produces only half
the expression or produces an error message.
All the best and sorry for a trivial quastion

try the following:
x <- runif(100, -4, 4)
y <- 1 + 2 * x + rnorm(100, sd = 2)
fit <- lm(y ~ x)
plot(x, y)
abline(fit)
legend("topleft", expression(paste(R[adj]^2, " = 0.66")))
## or
plot(x, y)
abline(fit)
legend("topleft", legend = substitute(R[adj]^2 == x,
list(x = summary(fit)$adj.r.squared)))
I hope it helps.
Best,
Dimitris

Hi CG,
move one of the parens:
legend("topleft", expression(paste(R[adj]^2, " = 0.66")))
Cheers
