I'm trying to plot a fitted lm() line on a plot when the one
explanatory variable is log transformed and log="x". I get different
lines using abline and predict.lm().
x <- 1:100
y <- rnorm(100)
plot(y ~ x, log="x")
abline(lm(y ~ log(x)))
lines(x, predict(lm(y ~ log(x))), lwd=2)
I'm sure I'm missing something but could someone tell me which line is
