I am a very new user of R, trying to do a linear fit to data,
plot(r2,d)
plots my data correctly, I do a linear fit:
res = lm(r2~d)
gives a fit to the data, but
abline(res,col=“red”)
displays nothing. Again, I am a novice, but what am I doing wrong?
Mixing up your x and y coordinate. Do:
plot(d,r2)
abline(res,col="red")
and all will be in harmony in the Universe.
