Hi R users,
I have some data points (Xi, Yi), and they may follow such a pattern Yi =
cCOS(Xi) + d, how to find the c and d in R? which function to use? Also,
how to get the R2 and p value for this correlation? Thanks for any kind of
help.
If I understand you correctly (always a dubious conditional):
fit <- lm(y ~ cos(x))
where y and x are vectors of the y and x values of your data points,
should answer all of your questions.
I am bewildered that you need to ask. You have been posting to this
list for quite a while. Have you learned nothing about R? It's time
that you did. Read and study carefully "An Introduction to R" from the
R web site -> Manuals.
cheers,
Rolf Turner
