Hello,

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().

#Example

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 correct? Thanks.

Richard
