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

You are using two different x's and one has nothing to do with the other.
All of your examples are simply internally inconsistent so there is no
reason to think they would work.

Hi,
I found some bottlenecks in my R code with Rprof. First I wanted to
rewrite them in C, but a colleague keeps suggesting that I learn
Fortran, so maybe this is the time to do it...
I like to learn new languages and do it fairly quickly. I would
appreciate the advice of others about these

See ?rconst in package ade4. You will need to fit the PCA with
dudi.pca (same package).

The simplest way to do this is to put
options(prompt = R )
in your .Rprofile file. If you don't have an .Rprifile file,
then persuading Windows to let you call a file by that name can
be frustrating. I suggest you delegate the job to R itself and
use something like this
