Hi R-listers,
I am having trouble plotting the values for the R2 line, lowess smooth,
smothered conditional spread, outlier identification.
I have tried the function text and legend but was unsuccessful. Please see
below.
Your help would be appreciated. Thanks in advance.

SPHSHTL<- scatterplot(HSuccess ~ HTL,
+ data = data.to.analyze,
+ xlab = "Distance to high tide line (metres)",
+ ylab = "Hatching success (%)")
legend("topright", bty="n", legend=paste("R2 is",
+
format(summary(SPHSHTL)$adj.r.squared, digits=4)))
scatterplot() does not return anything useful, and in particular it does
not include any element called "adj.r.squared".
I think you want to fit a model using lm() or so and proceed from there?

$ operator is invalid for atomic vectors
